DEFBUG(HLT,ABKSKD,PAGEM,SOFT,<ADDRESS BREAK FROM SCHEDULER CONTEXT>,,<
Cause: A page failure occurred while the monitor was running in scheduler
context, and the page fail word indicated an address break. Address
break can only be set in code that runs in process context.

DEFBUG(CHK,AN2BG1,IMPPHY,SOFT,<AN22 bug>,<<T1,BSEL0>,<T2,SEL2>,<T3,CALLER>>,<
Cause: An inconsistent condition in the AN22 has been detected, such as
interrupting when no interrupts were expected.
Action: These can be caused by races between the interrupt routines in
the 2020 and the AN22 microcode. They occur a few times a day
with apparently no ill effect. Unless they occur extremely
often, or in conjunction with other (ARPANET-related) bugs,
they can be ignored.
Data: BSEL0 and SEL2 are the contents of BSEL0 and SEL2 in the AN22's KMC11.
CALLER is the PC of the routine which detected the condition.

DEFBUG(CHK,AN2CEX,IMPPHY,SOFT,<Checksum error in transfer block for AN22 microcode>,,<
Cause: A checksum error was detected in the transfer block for the AN22
microcode (PS:<SYSTEM>AN22.MICROCODE).
Action: Try obtaining a new copy of the microcode; the copy which the monitor
attempted to load was either copied or built incorrectly.
To force the monitor to load the microcode while the system runs,
shut the ARPANET off and back on again (with ^ESET ARPANET ON/OFF).
Data:

DEFBUG(CHK,AN2CFM,IMPPHY,SOFT,<Can't GTJFN PS:<SYSTEM>AN22.MICROCODE>,<<T1,LSTERR>>,<
Cause: The AN22 driver could not get a JFN on PS:<SYSTEM>AN22.MICROCODE.
This could be caused by absence of that file or by disk trashage.
Action: Check to see that the file exists in the proper place. If it does,
check the state of PS: to insure that a GTJFN will succeed on the file.
Data: LSTERR is the monitor's error code returned from the failing GTJFN.
>)
DEFBUG(CHK,AN2CKS,IMPPHY,SOFT,<Checksum error loading AN22 microcode>,,<
Cause: A checksum error in the AN22 microcode was detected. This means
that the microcode file is bad.
Action: Apparently the microcode for the AN22 (PS:<SYSTEM>AN22.MICROCODE)
was either built or copied incorrectly. Obtain and install a new
copy of the microcode. To force the monitor to load the microcode,
shut the ARPANET off and back on again (with ^ESET ARPANET ON/OFF).
Data:
>)
DEFBUG(CHK,AN2COM,IMPPHY,HARD,<Can't OPENF PS:<SYSTEM>AN22.MICROCODE>,<<T1,LSTERR>>,<
Cause: The OPENF for PS:<SYSTEM>AN22.MICROCODE failed. This indicates
either disk trashage.
Action: Check the state of PS: to insure that it isn't trashed.
Data: LSTERR is the monitor's error code returned by the failing OPENF.

DEFBUG(CHK,AN2DNS,IMPPHY,SOFT,<DRAM loading not supported>,,<
Cause: The AN22 microcode file contains DRAM frames. The AN22 driver
cannot load DRAM into the KMC11.

built or copied incorrectly. Install a new copy.
Data:
>)
DEFBUG(CHK,AN2HNG,IMPPHY,HARD,<AN22 hung>,<<T1,BSEL0>>,<
Cause: The AN22 microcode is hung: it refuses to respond to commands.
Action: This probably indicates either bad microcode in the AN22, or
a hardware problem in the AN22's KMC11.
Data: BSEL0 is the contents of BSEL0. It contains the most recently
attempted command code.
>)
DEFBUG(INF,AN2IER,IMPPHY,SOFT,<IMIERR called>,<<T1,SEL2>>,<
Cause: This means that the IMP has dropped its ready line (IMP RDY).
This can be caused by any one of several things:
o The IMP has crashed.
o The IMP has declared the host tardy. This means
that the 2020 has not been accepting data from
the network fast enough.
o The handshaking between the 2020 and the IMP has
gotten out of synch.
Action: Since this is really a catch-all error message, no specific
recommendations can be made. To analyze the situation further,
see what other BUGCHKs or BUGINFs are occurring. If the IMP
is crashing, contact the Network Control Center at BBN (phone
(617) 661-0100).
Data: SEL2 is the contents of the SEL2 register in the AN22. It contains
status bits relevant to the IMP/Host interface. See the AN22
functional specification for a description of these bits.

DEFBUG(CHK,AN2MCV,IMPPHY,HARD,<AN22 microcode verify error>,<<T1,DESIRD>,<T2,ACTUAL>>,<
Cause: The AN22 driver read different data from the AN22's KMC11 CRAM
than the data it has just loaded.
Action: This indicates a hardware malfunction in the AN22's KMC11.
Data: DESIRD is the data the 2020 attempted to load. ACTUAL is what
was read out of the same location.

DEFBUG(INF,AN2OVF,IMPPHY,HARD,<AN22 input data overflow>,,<
Cause: The IMP sent a message to the 2020 which is longer than the
maximum allowable message size. This could indicate either
a malfunction in the IMP (hardware or software), a hardware
malfunction in the AN22, or a software bug in the AN22 driver.
Action: Investigate further.
Data:
>)
DEFBUG(CHK,AN2UCV,IMPPHY,SOFT,<AN22 microcode version skew>,<<T1,ACTUAL>,<T2,DESIRD>>,<
Cause: A different version of microcode than what the AN22 driver expects
has been installed.
Action: Check to make sure that you have the correct version of the microcode.
Data: ACTUAL is the microcode loaded. DESIRD is the version of microcode
for which the monitor was built.

DEFBUG(HLT,APRAPE,APRSRV,HARD,<ADDRESS PARITY ERROR>,,<
Cause: An APR interrupt occurred because a memory controller
signaled that it had received from the processor an
address with even parity. The monitor has printed a
description of the problem on the CTY.
>)
DEFBUG(HLT,APRNX1,APRSRV,HARD,<NXM DETECTED BY APR>,,<
Cause: An APR interrupt occurred because the processor attempted to
access a memory that did not respond within a preset time. This
can indicate broken hardware or a software bug. The monitor
has printed a description of the problem on the CTY.
Action: The analysis of this BUGHLT is extremely complicated.
The physical address from the error register is printed on the
CTY ("ERA="). If there is physical memory at this address, the
problem is probably in the hardware. If the address does not
exist, the probelm may be in either hardware or software.
One software problem that has led to this BUGHLT in the past
is code that returns an SPT slot to the free pool while leaving
a pointer to that slot in some page table. The content of
the SPT entry, instead of being a pointer to memory, is a
pointer to another SPT slot. In this case, a page fault will
have occurred just before the interrupt. The PC will point
into the page fault handler, and the page
fault word and PC (TRAPSW and TRAPPC, respectively) will
indicate the virtual address and instruction at the time of
the page fault. Tracing this virtual address to the SPT will
produce the erronenous SPT entry.
>)
DEFBUG(HLT,APRNX2,APRSRV,HARD,<NXM DETECTED BY APR>,,<
Cause: A page fault occurred indicating that the processor
attempted to access a memory that did not respond within
a preset time, and the monitor is presently processing an
interrupt or running in the scheduler, and the interrupt
system is turned on. Since non-existent memory also
produces an APR interrupt, which results in an APRNX1 BUGHLT,
this BUGHLT does not normally occur.
Action: Check the physical address to see if the memory exists. If
it does, the problem is most likely a software bug.

DEFBUG(HLT,ASGFR0,FREE,HARD,<ASGFRE - ILLEGAL TO ASSIGN 0 FREE SPACE>,,<
Cause: An illegal request for free space is being made. The caller
is asking for zero words of free space.
Action: Look at the dump. By backing up the stack you
should be able to tell what routine called for the illegal
free space.
>)
DEFBUG(CHK,ASGINT,FREE,HARD,<ASGFRE CALLED OKINT>,<<C,D>>,<
Cause: This is a free space problem. All calls to swapable free space routines
should be while NOINT. The calling routine is not protecting itself
from loosing free space. It is OKINT. Since it is OKINT it could
get interupted an never return, thus loosing the free block assinged.
Action: The data supplied gives the address of the calling routine. Make
the routine be NOINT untill it has ensured that the block will be
free'd when it is interrupted (e.g. JSB stack).
>)
DEFBUG(CHK,ASGREP,FREE,HARD,<ILLEGAL PRIORITY GIVEN TO ASGRES>,,<
Cause: This is a free space problem. The caller is asking for resident
free space. In T3 the caller gives a priority for this request.
The priority determines how ASGRES is going to handle this request
when free space is low. This priority is out of range.
Action: If the problem persists change the BUGCHK to a BUGHLT and look
through the dump to find the caller.
>)
DEFBUG(CHK,ASGREQ,FREE,HARD,<ILLEGAL POOL NUMBER GIVEN TO ASGRES>,,<
Cause: This is a free space problem. The caller is requesting resident
free space. In T2 the caller is providing a pool number for where
the free space should come from. This pool number is incorrect.
Action: If the problem persists change the BUGCHK to a BUGHLT to find the
culprit. The caller putting a bad value into T2.
>)
DEFBUG(HLT,ASGSW2,PAGEM,SOFT,<SWPOMG-CAN'T ASSIGN RESERVED DRUM ADDRESS>,,<
Cause: The monitor is swapping a group of pages to a set of contiguous
pages in the swapping space. The swapping space manager has
provided a starting address for a block of free pages. An attempt
to assign one of the pages has failed. This indicates an
inconsistency in the monitor's data or a race condition.
For example, a context switch may have occurred when it was
not expected.

Cause: One of the following failures occurred while trying to
reconstruct the root directory during system startup: couldn't
ge ofn for backup root-directory, couldn't get ofn for root-directory,
couldn't assign a page in the job data area to build the backup
index block, or the backup root-directory is clobbered.
>)
DEFBUG(HLT,BADROT,FILINI,HARD,<FILIN2: ROOT-DIRECTORY IS INVALID>,,<
Cause: While the system was coming up, BLKSCN is called to
check the consistency of the root directory. If BLKSCN takes the
error return, BADROT occurs, meaning that some block in the root
directory had an unrecognizable type, or the last block didn't end
at the right spot, or some block had an incorrect format.
Action: Using EDDT to break after BLKSCN and examine the error code in
AC1 will sometimes give a hint as to what is wrong with the root
directory. Also, there may be informative bugchks or buginfs too.
If the system can be brought up using another structure as PS:,
the bad structure can sometimes be fixed with various tools such
as FILDDT. If this restoration fails, the pack can be started
afresh and pertinent DUMPER backup tapes can be used to restore the
structure.

DEFBUG(HLT,BADTYP,TAPE,HARD,<BAD LABEL FIELD DESC>,,<
Cause: This is a bug in TAPE. The internal routines in TAPE have a table

out of range.
Action: Try to find out where the out of range code came from.

DEFBUG(HLT,BADXT1,FILINI,soft,<INDEX TABLE MISSING AND CAN NOT BE CREATED>,,<
Cause: During system startup, MAKIDX failed to recreate the index

>)
DEFBUG(HLT,BKUPDF,PAGEM,SOFT,<BKUPD - BAD CST1 ENTRY OR INCONSISTENT CST>,,<
Cause: A routine has been called to swap a core page to disk or drum.
It has decided to swap to the disk. The BUGHLT indicates that
no back address was found in the CST. This usually indicates
bad data in the CST or a bad pointer in a page table.
>)
DEFBUG(CHK,BLKF1,IO,HARD,<BYTINA: BLKF SET BEFORE CALLING SERVICE ROUTINE>,,<
Cause: This is a consistancy check in BYTINX. The enviornment is in IO where sequential
input is being processed. The code is getting ready to jump to the
device dependant code. Before doing so it sees if a bit (BLKF) is
set in STS (AC 8). This bit indicates that the service routine wants
to block. Therefore, no matter what the device dependant routines
do the process will ultimately block. It is unlikely that this is
being done on purpose. It is more likely that somewhere BLKF is
not being cleaned up prolerly.
Action: If this is becoming a problem change the BUGCHK to a BUGHLT and
look at the dump.If FILSTS for the current JFN has the bit on then
the problem gets a little tricky since the previous use of it left
BLKF on. If BLKF is off in FILSTS then somewhere past the call to
CHKJFN it is being turned on.
>)
DEFBUG(CHK,BLKF2,IO,HARD,<BYTOUA: BLKF SET BEFORE CALL TO SERVICE ROUTINE>,,<
Cause: This is a consistancy check in BYTOUA. The environment is in IO just
before it gets ready to call the device dependant routines to do output.
Bit BLKF in STS (AC 8) is on. It should be off. It causes the process
to block. It is unlikely that this sort of apriori knowledge is
available. It is more likely that this is an error.
Action: If the problem persists change the BUGCHK to a BUGHLT and look at
the dump. If FILSTS for the current JFN has the BLKF bit on then
the last one to user the JFN left it in that state. A hard problem
to find. If BLKF is off in FILSTS then somewhere after the call to
CHKJFN the bit is being set on not reset.

the difference between the halves of the contents of BUTPGS, then
subtracts out the contents of SUMNR.
>)
DEFBUG(HLT,BOOTER,MEXEC,hard,<GETSWM - ERROR LOADING SWPMON>,,<
Cause: The monitor calls BOOT with a JSP CX,777(T2) in order to
load a section of the swappable monitor. This transfers to
the VBOOT tag within BOOT, which does the work and takes a
skip return if there are not errors.
It takes a non-skip return if there is an error, in which case
BOOTER results.
Action: BOOTER has been observed when memory parity errors exist, so
check for this and do memory corrective maintenance.
>)
DEFBUG(HLT,BOOTLK,MEXEC,soft,<GSMDSK - FAILED TO LOCK NEEDED PAGES>,,<
Cause: CGPLK is called three times during the booting of the

BOOT's ept, and lastly to lock the swappable monitor's area.
If any of the calls to CGPLK fail, BOOTLK occurs.

DEFBUG(HLT,BTBCR1,FILINI,soft,<FILINI - NO BIT TABLE FILE AND UNABLE TO CREATE ONE>,,<
Cause: MNTBTB failed, so the system restart logic called CRTBTB to
create a new bit table. CRTBTB failed too, so the BTBCR1 bughlt
happened. CRTBTB will fail if INIBTB fails, which can happen if
DSKASA fails to assign a disk page, or if SWPASN fails to assign
swapping space.

DEFBUG(HLT,BTBCRT,FILINI,soft,<FILINI - COULD NOT INITIALIZE BIT TABLE FOR PUBLIC STRUCTURE>,,<

CRTBTB failed to build a new bit table. See CRTBT1 for more detail

DEFBUG(HLT,CST2I1,PAGEM,SOFT,<PAGE TABLE CORE POINTER AND CST2 FAIL TO CORRESPOND>,,<
Cause: A routine has been called to change the map for a page of a
process. The page is being mapped to a file pge that is not
already shared. The code is going to create an entry for the
file page in the SPT so that the destination can have a
share pointer. The page pointer in the index block contains
a core address. The BUGHLT indicates that the owner of the
core page is not the file pge that points to it. This means
that there is an inconsistency in the monitor's data.
>)
DEFBUG(HLT,CST2I2,PAGEM,SOFT,<MVPT-CST2 INCONSISTENT>,,<
Cause: A routine has been called to move a page from one page table
to another. The source page table has an immediate pointer to
a page in memory. The BUGHLT indicates that the CST entry for
that page contains a different owner from the source id that
points to it. This indicates an inconsistency in the monitor's
data.

DEFBUG(HLT,CST2I3,PAGEM,SOFT,<PAGE TABLE CORE POINTER AND CST2 FAIL TO CORRESPOND>,,<
Cause: A routine has been called to remove a page from a process's

SPT entry to which the map points contains a core page number.
The BUGHLT indicates that the CST entry for that core page
does not point back to the SPT entry.

This bugchk announces that the system is assuming that some fork has
neglected to unlock the fork lock, and the waiting fork is being
given the lock even though someone else still has it.
The code could be in error here. The measure of a "long time" is
calculated according to how many times the lock has been asked for

of forks desiring the lock. Hence the FLKTIM could occur falsely if
many forks are all trying to get the fork lock at the same time.

include illegal read, write, and section number. See the page
fail word for the reason code.
This BUGHLT can also occur if an unrecoverable AR/ARX parity

1. The page is not in core.
2. The page is part of the resident monitor.
3. The page is locked in memory.
4. The page is already being swapped.

not point to the monitor's map or pointed to an existing page
in the monitor's map.
>)
DEFBUG(HLT,ILPPT1,PAGEM,HARD,<UPDOFN-BAD POINTER IN PAGE TABLE>,,<
Cause: The monitor is updating on the disk the index block for a file.
The index block contains an address of a file page that is
incorrect for one of the following reasons:
1. It is a memory address of non-existent memory or in the
resident monitor.
2. There is no disk address for the page.
>)
DEFBUG(HLT,ILPPT3,PAGEM,SOFT,<BAD POINTER IN PAGE TABLE>,,<
Cause: A page fault occurred because a process touched a page whose
map entry contained access bits of 0, indicating non-existent
page. But when the monitor mapped the page table, the page's
entry was not 0. A non-existent page should always be
represented by an all-zero entry.
>)
DEFBUG(HLT,ILPSEC,APRSRV,HARD,<ILLEGAL SECTION NUMBER>,<<TRAPPC,PC>,<TRAPSW,PFW>>,<
Cause: While running in scheduler context, the monitor made a

associated with the pge. The BUGHLT occurs because the caller has
passed a 0.
>)
DEFBUG(HLT,ILRBLT,PHYSIO,HARD,<PHYSIO - IORB LINK NOT NULL AT ONF/STWQ>,,<
Cause: One of the routines ONFTWQ or ONSTWQ was called to insert an IORB
into the transfer wait queue, but the link word for that IORB
was not zero. IORBs should always contain a null link when
they are created or removed from a queue, so that many queue
handling errors can be detected.
>)
DEFBUG(HLT,ILRFPD,PAGEM,SOFT,<PDL-OV IN ILLEGAL PAGE REFERENCE>,,<
Cause: The monitor made an illegal reference to an address and was
prepared to handle the error. However, its stack overflowed in
processing the error.

DEFBUG(HLT,ILSPTH,PAGEM,SOFt,<SETPT-SPTH INCONSISTENT WITH XB>,,<
Cause: A routine has been called to change the map for a page of a
process. The page is being mapped to a file page for which
the index block has a share pointer. The share pointer points
to an SPT slot. The BUGHLT indicates that the SPT slot is not
owned by the file page whose map word points to it. This
indicates an inconsistency in the monitor's data.
>)
DEFBUG(HLT,ILSPTI,PAGEM,SOFT,<ILLEGAL SPT INDEX GIVEN TO SETMXB>,,<
Cause: A routine has been called to change the map for a page. The
caller provided a source id for a page table (i.e., an SPT
index) rather than a single page. The BUGHLT indicates that
the source id is an invlid SPT index, larger than the
maximum value.
>)
DEFBUG(HLT,ILSRC,PAGEM,SOFT,<ILLEGAL SOURCE IDENTIFIER GIVEN TO SETPT>,,<
Cause: A routine has been called to change the map for a page. The
caller is expected to provide an identifier for the source
that is of the form (SPT index,,page number). The BUGHLT
indicates that the right half of the id contains an illegal
value (i.e., exceeds 777).
>)
DEFBUG(HLT,ILSTP3,LOOKUP,SOFT,<VERLUK: IMPOSSIBLE SKIP RETURN FROM EXTLUU>,,<

DEFBUG(HLT,ILTWQ,PHYSIO,HARD,<PHYINT - TWQ OR PWQ INCORRECT>,,<
Cause: In the PHYINT routine to handle an interrupt, after the lower

the IORB returned matched the first element of either the position
wait queue or the transfer wait queue. It did not.
>)
DEFBUG(HLT,ILTWQP,PHYSIO,HARD,<PHYSIO - PWQ OR TWQ TAIL POINTER INCORRECT>,,<
Cause: The pointer to the last element in the position wait queue or
transfer wait queue (UDBPWQ or UDBTWQ) points to an IORB which
has a non-null link to further IORBs. This is checked in various
routines such as ONTWQ, ONPWQ, ONSTWQ, ONFPWQ, CONSTW, or CONSPW.

DEFBUG(HLT,ILULK2,PAGEM,SOFT,<TRIED TO UNLOCK PAGE NOT LOCKED>,,<
Cause: A routine was called to unlock a core page. But the page's
lock count was 0.

DEFBUG(HLT,ILULK3,PAGEM,SOFT,<MULKMP - ILLEGAL MONITOR ADDRESS>,,<
Cause: A routine was called to unlock a core page in the monitor's
address space. But the caller provided a page id that did not
point to the monitor's map.
>)
DEFBUG(HLT,ILULK4,PAGEM,SOFT,<MULKCR - ILLEGAL CORE PAGE NUMBER>,,<
Cause: A routine was called to unlock a core page. The caller provided
a page number that was illegal because either
1. The page is never locked because it is part of the resident
monitor
or
2. The page does not exist in physical memory.
>)
DEFBUG(HLT,ILUST1,PHYSIO,HARD,<PHYSIO - UNIT STATUS INCONSISTENT AT SIO>,,<

Data: The data item displayed is a CONI ANI.
>)
DEFBUG(INF,IMINX2,IMPPHY,HARD,<IMIERR CALLED, CONI ANI IS>,<<T1,CONIAN>>,<
Cause: The IMP dropped its ready line, possibly only momentarily. The
IMP will drop its ready line if the 20 is tardy (takes more than
15 seconds to accept data from the IMP), or if the IMP believes
the 20 to be down.
Action: Check the hardware and cabling between the IMP and the 20.
Check to be sure the IMP has not stopped running.

routine.
>)
DEFBUG(HLT,IONXM,APRSRV,HARD,<I/O NXM ON UNIBUS DEVICE>,,<
Cause: This bughlt can only happen on the 2020. It means a unibus
address referenced in an IO instruction, such as RDIO, WRIO, TIOE etc.,
did not exist.
Nonexistent unibus address references generate a page fail code 20.
The 2020 code checks to see if the PI system is on, and if so, the
bughlt occurs. The 2020 has a routine called UBGOOD to test to see
if a unibus address exists (used to see what devices are connected).
The UBGOOD routine turns the PI system off so that it can test for
a nonexistent unibus address without crashing the machine.
>)
DEFBUG(HLT,IOPGF,APRSRV,SOFT,<IO PAGE FAIL>,<<Q1,PFW>>,<
Cause: An APR interrupt occurred because an interrupt instruction caused
a page failure. This probably indicates that the interrupt instruction
provided by the monitor referenced a page that was not in memory.
The monitor has already checked for a DTE that caused it and
found none.
The monitor
has printed a description of the problem on the CTY. A SYSERR
block has been created and will be placed in the SYSERR file
when the monitor is rebooted.

of an entry in PIDTBL. This BUG should appear the first time the

DEFBUG(HLT,KPALVH,APRSRV,SOFT,<KEEP ALIVE CEASED>,,<
Cause: The immediate cause of this BUGHLT is the execution of
location 71. The front end does this if the monitor has
not updated its keep-alive counter recently. This usually
indicates that the monitor is looping and preventing the
scheduler from running. This can be due to a software
bug or hardware that interrupts abnormally frequently.
This BUGHLT can be caused manually by requesting the
front end to execute location 71.
Action: Look at the CTY output to see which case occurred. Look at
the PC in the optional data to see where the monitor was
running. If the crash was done manually, the PC will
contain 72.

Note that the hardware reference manual incorrectly states that
an LUUO in exec mode becomes an MUUO.

;-M-
DEFBUG(HLT,MAP41F,FORK,soft,<MAPF41 FAILED TO SKIP>,,<
Cause: The MAPFKH routine calls itself recursively in order to
find every fork in a specified tree. For each fork found, the
instruction following the call to MAPFKH is executed. MAPFKH
finally skip-returns in order not to fall into that coinstruction
at .+1. The recursive calls skip-return too, merely because they
fall through the same RETSKP instruction.
The MAP41F bughlt should never happen, and is merely a placeholder
for the impossible non-skip return from the recursive call to
MAPFKH.

error. However, the BUGHLT indicates that the second error
(caused by the retry) was not an AR or ARX parity error and

the IPCF message. The user program involved will get an error
return to its tape operation.
Action: There are many reasons IPCF refuses to send a message. The IPCF error
code is passed back to the user. If it is a resource problem try
to imptove system resources. If it seems like a monitor bug change
the BUGINF to a BUGHLT and find out what the monitor is doing wrong

DEFBUG(HLT,OFFSPE,PAGEM,SOFT,<OFFSPQ- PAGE NOT ON SPMQ>,,<
Cause: A routine has been called to remove a core page from the special

DEFBUG(HLT,OVFLOW,PAGEM,SOFT,<ASOFN - ALLOCATION TABLE OVERFLOW>,,<
Cause: The monitor maintains information for disk quota enforcement
in two parallel tables called the "allocation tables". These
contain one entry for each direcory to which at least one OFN
is assigned (i.e., there is at least one open file). The size
of these tabls is the maximum number of OFN's; therefore even
if every OFN were associated with a unique directory, there
should be enough room in the allocation tables. The BUGHLT
indicates that the tables have overflowed.

DEFBUG(INF,OVRDTA,PHYSIO,HARD,<PHYSIO - OVERDUE TRANSFER ABORTED>,<<T1,CHAN>,<T2,CONTRL>,<T3,UNIT>>,<
Cause: In the routine UNICKT to check the status of each unit periodically,
some unit had an active IORB which timed out. The IO operation had
been started, but not completed within 17 seconds. This BUGINF can
be followed by other BUGINFs or BUGCHKs when the device finally
responds (such as PH2DNA).
Action: If the involved device is a tape drive controlled by a DX20, a
common cause of the BUGINF is the microcode halting. Reloading
the microcode will fix the problem. Other causes are hardware
failures, and field service should examine the problem.
Data: CHAN/ The channel number.
CONTRL/ The controller number (-1 if no controller).
UNIT/ The unit number.

DEFBUG(HLT,PAGLCK,PAGEM,SOFT,<DESPT-PAGE LOCKED>,,<
Cause: The monitor is attempting to deassign a slot in the non-OFN
part of the SPT tables. The caller is expected to ensure that
the SPT is no longer in use. The BUGHLT indicates that the
SPT slot is associated with a page that has been locked into
memory even though the SPT share count is 0. This indicates
an inconsistency in the monitor's data base. Probably the page
was used as a page table, and not all its page pointers were
cleared properly. A page table is locked in memory once for
each page in memory to which it points.
>)
DEFBUG(HLT,PAGNIC,PAGEM,SOFT,<GETCPP-PAGE NOT IN CORE>,,<
Cause: A routine was called to convert a virtual address or page id
to its corresponding core page. But the page table is not in
core.

DEFBUG(INF,PH2DNA,PHYH2,HARD,<PHYH2 - DONE INTERRUPT AND CHANNEL NOT ACTIVE>,<<T2,CHAN>>,<
Cause: The routine RH2INT was called to handle an interrupt on the
RH20 and the CONI said done was up, but no IO transfer was
in progress. If an OVRDTA had previously occured, and the
device finally responds, this BUGINF can happen. This usually
indicates a hardware failure.
Action: Call field service.
Data: CHAN/ The channel number.
>)
DEFBUG(CHK,PH2IHM,PHYH2,HARD,<PHYH2 - ILLEGAL HDW MODE - WORD MODE ASSUMED>,,<
Cause: The routine RH2CCW was called to generate a channel transfer

the data mode supplied was illegal.
>)
DEFBUG(CHK,PH2PIM,PHYH2,HARD,<PHYH2 - RH20 LOST PI ASSIGNMENT>,<<T2,CHAN>>,<
Cause: The routine RH2CHK was called for a periodic check on the status
of the RH20, and it discovered that the channel assignment of
the RH20 changed from what it should be. This usually indicates
a hardware malfunction.
Action: Call field service.
Data: CHAN/ The channel number.
>)
DEFBUG(HLT,PH2WUI,PHYH2,HARD,<WRONG UNIT INTERRUPTED>,,<
Cause: The routine RH2INT was called to handle an interrupt, and it
determined that IO had finished for a unit. But the unit
the CONI said did the IO was not the one we supposedly started
IO to, and the operation was a write operation. This BUGHLT
occurs on the second such error for a particular IORB.
>)
DEFBUG(HLT,PHYCH1,PHYSIO,HARD,<PHYSIO - HOME BLOCK CHECK IORB ALREADY ON TWQ>,,<
Cause: The SCHXFR routine was called to select the next IORB for IO on
a channel, and one of the units needed it's home blocks checked.
Then in moving the special home block IORB onto the front of the
transfer wait queue, it was noticed that the IORB was already on
the queue.
>)
DEFBUG(INF,PHYCH2,PHYSIO,HARD,<PHYSIO - HOME BLOCK CHECK IORB TIMED OUT>,,<
Cause: In the PHYCHK routine to check the status of all units, the
special home block check IORB was discovered to be overdue.
See OVRDTA for additional information.
>)
DEFBUG(INF,PHYCH3,PHYSIO,HARD,<PHYSIO - HOME BLOCK CHECK IORB TIMED OUT BUT WAS NOT ON TWQ>,,<
Cause: In the PHYCHK routine to check the status of all units, the
special home block IORB was discovered to be overdue. However,
the unit status indicated that the unit was not active, or the
first IORB on the TWQ was not the home block check IORB.
>)
DEFBUG(HLT,PHYICA,PHYSIO,HARD,<PHYINI - ILLEGAL ARGUMENT TO CORE ALLOC>,,<
Cause: The routine PHYALC was called asking for a nonpositive number
of words. This routine is called to allocate resident storage
for data such as CDB's, KDB's, and UDB's.
>)
DEFBUG(INF,PHYICE,PHYSIO,HARD,<PHYINI - FAILED TO ASSIGN RESIDENT STG>,,<
Cause: The routine PHYALC was called to allocate storage for data such
as a CDB, KDB, or UDB, but there was not enough free resident
storage to allocate it. The monitor will simply forget about
any device which it can't build tables for.
>)
DEFBUG(HLT,PHYLTF,PHYSIO,HARD,<PHYSIO - SCHLTM - UNEXPECTED LATOPT FAILURE>,,<
Cause: The routine SCHLTM was called to do disk latency optimization,
by looping over all units looking for the best IORB. A unit
was found to have a nonnull transfer wait queue, but the lower
level code to select the best IORB for that unit gave the
non-skip return, indicating that no IORBs existed.
>)
DEFBUG(CHK,PHYNIR,PHYSIO,HARD,<PHYSIO - NULL INTERRUPT ROUTINE AT OPERATION DONE>,,<
Cause: In the routine DONIRB when terminating a long IORB, an attempt
was made to notify higher level code about the finished IORB,
but the field in the IORB containing the address to call was zero.
>)
DEFBUG(HLT,PHYP0E,PHYSIO,HARD,<PHYALZ - PAGE 0 STORAGE EXHAUSTED>,,<

DEFBUG(CHK,PI1ERR,APRSRV,HARD,<UNEXPECTED UNVECTORED INTERRUPT ON CHANNEL 1>,,<
Cause: The monitor has received an unvectored hardware interrupt on PI

channel. This could possibly indicate faulty hardware that is
generating spurious PI requests.
>)
DEFBUG(CHK,PI2ERR,APRSRV,HARD,<UNEXPECTED UNVECTORED INTERRUPT ON CHANNEL 2>,,<
Cause: The monitor has received an unvectored hardware interrupt on PI

generating spurious PI requests.
>)
DEFBUG(CHK,PI4ERR,APRSRV,HARD,<UNEXPECTED UNVECTORED INTERRUPT ON CHANNEL 4>,,<
Cause: The monitor has received an unvectored hardware interrupt on PI

channel. This could possibly indicate faulty hardware that is
generating spurious PI requests.
>)
DEFBUG(CHK,PI5ERR,STG,hard,<UNEXPECTED UNVECTORED INTERRUPT ON CHANNEL 5>,,<
Cause: If no devices are supposed to exist on the system which cause
unvectored interrupts on channel 5, and more than ten such interrupts
happen, this bugchk will occur.
This bugchk is only possible if your system has no dectape and no
card punch and no papertape reader.
It has been observed that the DX20 occasionally causes random
interrupts. Having the bugchk not happen until ten such interrupts
have been received tends to prevent the bugchk from happening.

Cause: A page fault occurred while a hardware interrupt was in progress.
This can be the result of hardware failure or a software bug. If
the page fail word indicates an AR or ARX parity error, the monitor
has printed an analysis of the problem on the CTY, and a SYSERR
entry will be created when the monitor is rebooted.

Cause: This BUG is not documented yet.
Action:

DEFBUG(HLT,PRONX2,APRSRV,SOFT,<NXM DETECTED BY PROCESSOR>,,<
Cause: A page fault occurred indicating that the processor
attempted to access a memory that did not respond within
a preset time, and the monitor is presently running in
process context, and the interrupt system is on. Since
non-existent memory also produces an APR interrupt,
which results in an APRNX1 BUGHLT,
this BUGHLT does not normally occur.
Action: Check the physical address to see if the memory exists. If
it does, the problem is most likely a software bug.
>)
DEFBUG(HLT,PSBNIC,PAGEM,SOFT,<SETPPG-PSB NOT IN CORE>,,<
Cause: The monitor is establishing the context for running a
process by making its per process area be part of the

DEFBUG(HLT,PTAIC,PAGEM,SOFT,<SWPIN - PT PAGE ALREADY IN CORE>,,<
Cause: A routine has been called to swap a page into core. The id for
the page indicates that it is a data page. The BUGHLT
occurred because the entry in its page table contains a core
address.
>)
DEFBUG(HLT,PTDEL,PAGEM,SOFT,<DESPT-PT NOT DELETED>,,<
Cause: The monitor is attempting to deassign a slot in the non-OFN
part of the SPT tables. It assumes that the slot was used as a
page table. The BUGHLT occurs because the SPT entry or its
backup address is on disk. The caller probably has used the
wrong routine in releasing an OFN.
>)
DEFBUG(HLT,PTMPE,APRSRV,HARD,<PAGE TABLE PARITY ERROR>,,<
Cause: A page fault occurred indicating a page table parity error.
That is, the pager encountered a page table mapping with
incorrect parity.

DEFBUG(HLT,PTNIC1,APRSRV,SOFT,<SWPIN - PAGE TABLE NOT IN CORE>,,<
Cause: A routine has been called to map a page table into a special
page used only by the swapping routines. The caller is expected
to provide an identifier for a page that is in memory. When a
page is in memory, the page table that points to it must be
in memory. The BUGHLT indicates that the storage address for
the page table is not a valid core page. This can indicate
that the pge is not in meory or that is memory address is larger
than the physical memory on the machine.

DEFBUG(HLT,PTNON0,PAGEM,SOFT,<SETPT0 - PREVIOUS CONTENTS NON-0>,,<
Cause: A routine has been called to change the map for a page of a
process. The caller is expected to have unmapped any previous
contents of the page. The BUGHLT indicates that the page table
contains a non-zero pointer for the page.
>)
DEFBUG(HLT,PTOVRN,PAGEM,SOFT,<UPDPGS-COUNT TOO LARGE>,,<
Cause: A routine has been called to update on the disk pages of a
file pointed to by a specified index block (OFN). The caller
provides a starting page and a count. The BUGHLT occurs
because the sum of the two extends beyond the end of the
index block.
>)
DEFBUG(HLT,PVTRP,APRSRV,HARD,<PROPRIETARY VIOLATION TRAP>,,<
Cause: A page fault occurred indicating a proprietary violation while
the monitor was running in scheduler context. That is, an
instruction in a public page attempted to reference a
concealed page. Since TOPS-20 uses only concealed mode, this
BUGHLT should never happen.
>)
DEFBUG(HLT,PWRFL,APRSRV,HARD,<FATAL POWER FAILURE>,,<
Cause: The monitor has been started at the power-fail recovery
code and is attempting to recover. However, the loss
of power that preceded this occurred too quickly to
allow an orderly shutdown. Therefore the monitor will
be reloaded.
>)
DEFBUG(CHK,PWRRES,APRSRV,HARD,<POWER RESTART>,,<
Cause: The monitor has been started at the power fail recovery code
and is attempting to recover. This BUGCHK will be followed by
one of the following messages:
"Attempting to continue system"
"PWRDWN .NE. -1, restarting"
The first will be printed if an orderly shutdown was
accomplished before the power fail. If so, the system will
continue. Otherwise, the second message will be printed,
the monitor will BUGHLT, and the front end will reload
the monitor.
>)
DEFBUG(HLT,PYILUN,PHYSIO,HARD,<PHYSIO - ILLEGAL UNIT NUMBER>,,<
Cause: The routine SETUDB was called to find the UDB and KDB pointers
given the CDB and unit number, but the unit number given was
out of range.
>)
;-Q-
;-R-
DEFBUG(CHK,RCVNOE,JSYSA,SOFT,<RCVOK - NO ENTRY FOUND IN QUEUE>,,<
Cause: The RCVOK JSYS has detected that the list of unprocessed GETOK
requests is empty, but the count of entries in the list is nonzero.
>)
DEFBUG(CHK,RCVTMR,JSYSA,SOFT,<RCVOK TIMEOUT - IGNORING ACCESS CONTROL JOB>,,<
Cause: The access control job did not do a RCVOK within the designated time
period. A GETOK request was pending.
Action: The access control job should be examined to see if its receiving
requests can be made faster.
>)
DEFBUG(CHK,RELBAD,FREE,HARD,<RELFRE-BAD BLOCK BEING RELEASED>,<<CX,D>,<A,D>,<B,D>,<C,D>>,<
Cause: This is a free space problem. The block being returned does not fit
into the free space. When block are returned to the free space pool
there is a consistancy check preformed. The block is merged into
existing blocks that follow it in free space. This block overlaps
into existing free blocks. It can not be merged.
Action: If the problem persists change the BUGCHK to a BUGHLT. Looking at
the stack will show the caller. It is possible that the length of the
current block is incorrect. It is equally likely that the
block(s) before this block (in free space) have had incorrect
lengths on return. Thus, the caller may not be the culprit.
>)
DEFBUG(HLT,RELFRM,FREE,HARD,<ILLEGAL TO DEASSIGN 0 FREE SPACE>,,<
Cause: This is a free space problem. The caller is trying to release a block
of storage. Unfortunately, the length given is zero. It is illegal
to free a block of zero length.
Action: Look at the dump. Backing up the stack will show who it is that
made the call to release the storage.
>)
DEFBUG(CHK,RELINT,FREE,HARD,<RELFRE CALLED OKINT>,<<A,D>>,<
Cause: This is a free space problem. The calling routine is trying to release
a swapable free space block while it is OKINT. This is dangerous since
it could get interrupted and loose the block. All
free space actions should occur while NOINT.
Action: The data supplied gives the address of the calling routine. Make
the routine become NOINT when it removes the address of the block
about to be released from the database. The routine
can be made OKINT when control is returned to it.
>)
DEFBUG(HLT,RELRNG,FREE,HARD,<RELFRE: BLOCK OUT OF RANGE>,<<B,D>,<A,D>,<D,D>>,<
Cause: This is a free space problem. The caller to the free space
routines is trying to return a block that was not given
out by the free space manager. The block is outside the
range of free space management.
Action: Look through the dump. By looking at the stack you
should be able to determine who called for the releasing
of the block.
>)
DEFBUG(CHK,RESBAD,FREE,HARD,<RELRES: ILLEGAL ADDRESS PASSED TO RELRES>,,<
Cause: This is a free space problem. The caller is trying to release some
resident free space. The address being specified is not a legal
resident free space address.
Action: If the problem persists change the BUGCHK to a BUGHLT and find the
caller. The caller is providing an illegal address.
Find where the caller get the address and how that location gets
modified.
>)
DEFBUG(CHK,RESBAZ,FREE,HARD,<RELRES: FREE BLOCK RETURNED MORE THAN ONCE>,,<
Cause: This is a free space problem. The caller is returning a block to
residnet free space. The block being returned is already a released
block in the resident free space pool. Thus, the caller is either
returning the same block twice or has a completely random address which
is incorrect.
Action: If the problem persists change the BUGCHK to a BUGHLT. The caller
may or may not be the culprit. It is possible that some other
routine is picking up the wrong address and releasing it.
>)
DEFBUG(CHK,RESBND,FREE,HARD,<RELRES: RELEASING SPACE BEYOND END OF RESIDENT FREE POOL>,,<
Cause: This is a free space problem. The caller is trying to release resident
free space. The address passed to RELRES is outside the range of the
resident free space pool.
Action: If the problem persists change the BUGCHK to a BUGHLT.
>)
DEFBUG(CHK,RFILPF,APRSRV,HARD,<REFILL ERROR PAGE FAIL>,,<
Cause: A page fault occurred indicating a refill error. This condition
is indicated by bit 22 of the page fail word and should occur
only under KI-style paging. TOPS-20 does not use this style of
paging. The monitor will retry the instruction.
>)
DEFBUG(HLT,RH11CC,PHYH11,soft,<PHYH11 - ILLEGAL CHANNEL COMMAND WORD>,,<
Cause: This bughlt can only occur on the 2020.
This bughlt will happen if the CHSTRT routine encounters a address of 0
in the channel control word. The right half of the channel control word
is the address.
>)
DEFBUG(HLT,RH1ICF,PHYH11,soft,<PHYH11 - INVALID CHANNEL FUNCTION>,,<
Cause: This bughlt can only happen on the 2020.
The CHSTRT routine is called to perform disk operations. On the
call, Q1 is supposed to contain a function code, and T2 is supposed
to contain the value to be used for a DATAO. However, -1 in Q1
denotes that T2 contains the DATAO but that no function is to
be done.
The bughlt will occur if T2 is 0 or if T2 is non-0 and Q1 is 0,
which can only occur due to some caller supplying CHSTRT with
bad arguments.
>)
DEFBUG(HLT,RH2ICF,PHYH2,HARD,<PHYRH2 - INVALID CHANNEL FUNCTION>,,<
Cause: The routine CHSTRT was called to start IO on the channel,
but the supplied arguments were illegal. Either no DATAO
word was specified, or the function code was zero.
>)
DEFBUG(HLT,RP4FEX,PHYP4,SOFT,<PHYP4 - ILLEGAL FUNCTION>,,<
Cause: The routine RP4SIO was called to start IO for a unit, but
the function code supplied in the IORB was out of range.
>)
DEFBUG(HLT,RP4IF2,PHYP4,SOFT,<PHYP4 - ILLEGAL FUNCTION AT STKIO>,,<
Cause: The routine RP4STK was called to start stacked IO for a
unit, but the function code supplied in the IORB was out
of range.
>)
DEFBUG(HLT,RP4IFC,PHYP4,SOFT,<PHYP4 - ILLEGAL FUNCTION AT CNV>,,<
Cause: The routine RP4CNV was called to return the cylinder associated
with an IORB. The routine checked the function in the IORB, and
it was illegal.
>)
DEFBUG(HLT,RP4ILF,PHYP4,HARD,<PHYP4 - ILLEGAL FUNCTION ON INTERRUPT>,,<
Cause: The routine RP4INT was called by the channel routine to handle
a non-attention interrupt. The function code for the IORB that
IO was done for was either illegal, or else the function was
one which did not transfer data. Functions which don't transfer
data should give an attention interrupt.
>)
DEFBUG(HLT,RP4LTF,PHYP4,SOFT,<PHYP4 - FAILED TO FIND TWQ ENTRY AT RP4LTM>,,<
Cause: The routine RP4LTM was called to find the entry on the transfer
wait queue which had the best latency. But after searching the
queue, no IORB was found to return. This routine should only
be called when the transfer wait queue is nonempty.
>)
DEFBUG(HLT,RP4PNF,PHYP4,SOFT,<PHYP4 - DISK PHYSICAL PARAMETERS NOT FOUND>,,<
Cause: The routine RP4INI was called to initialize a UDB for a disk.
It converted the hardware drive type into the internal drive
type, and then looked in the physical parameter table (DSKUTP)
for that type, so that the disk parameters could be obtained.
The drive type could not be found.
>)
DEFBUG(CHK,RP4SSC,PHYP4,HARD,<PHYP4 - STUCK SECTOR COUNTER>,<<T1,D>,<T2,D>>,<
Cause: During initialization of a disk unit in the routine RP4INI,
the sector counter for the disk was examined to see if it
was changing as it should. After watching the value for
100000 times, it never varied.
Action: Call field service to fix the disk.
>)
DEFBUG(HLT,RP4UNF,PHYP4,HARD,<PHYP4 - UNIT TYPE NOT FOUND:>,<<T1,D>>,<
Cause: During initialization of a disk in the routine RP4INI, the
hardware drive type of the disk was read, and then the XTYPE
table was searched to convert it to the internal drive type.
The search failed, indicating the disk was of an unknown type.
>)
DEFBUG(HLT,RPGERR,PAGEM,HARD,<BADCPG-FATAL ERROR IN RESIDENT PAGE>,,<
Cause: A hardware error (AR/ARX parity error or MB parity error) was
detected when the monitor referenced a page in memory that
contained part of the resident monitor. The monitor has printed
an analysis of the error on the CTY, and A SYSERR entry will be
created when the monitor is rebooted.
>)
DEFBUG(HLT,RSMFAI,PAGEM,HARD,<RESSMM-FAILED TO ASSIGN SWAP MON PAGE>,,<
Cause: The monitor is trying to restore the swappable monitor from the
swapping space after a system crash. It is unable to assign a
page in the swapping space to which a monitor page was previously
written. Note: This code is executed only if the monitor is
manually started at location EVLDGO. This is not a recommended
procedure.
>)
;-S-
DEFBUG(INF,SBSERF,APRSRV,SOFT,<SBSERR-COULD NOT GET ERROR BLOCK>,,<
Cause: An APR interrupt occurred because a memory controller detected
an error in its own operation or in information received over
the S bus or from a memory module. The monitor has determined
that a MOS controller is involved. Normally the monitor creates
a block and records information about the error for later
retrieval by TGHA. However, no free space is available, so this
information will be lost.

Cause: This BUG is not documented yet.
Action:
>)
DEFBUG(HLT,SCPT01,PAGEM,SOFT,<SCNPT - ENTRY IS NOT AN IMMEDIATE POINTER>,,<
Cause: A routine has been called to release all pages pointed to by a
specified page table. The caller must ensure that all pointers
are immediate pointers to core with no disk backup. The BUGHLT
indicates that a pointer was not an immediate pointer.
>)
DEFBUG(HLT,SCPT02,PAGEM,HARD,<SCNPT - PAGE WAS NOT DELETED>,,<
Cause: A routine has been called to release all pages pointed to by a
specified page table. The caller must ensure that all pointers
are immediate pointers to core with no disk backup. The BUGHLT
indicates that a page had backup on disk.

DEFBUG(HLT,SECEX1,PAGEM,SOFT,<SETMPG-ATTEMPT TO MAP NON-EX SECTION>,,<
Cause: A routine has been calld to modify a process's map for one
or more pages. A virtual address was provided. The caller is
expected to provide a valid address. The BUGHLT indicates that
a section that does not exist in the process's map was
specified.

Cause: This BUG is not documented yet.
Action:

DEFBUG(HLT,SHRNO0,PAGEM,SOFT,<DESPT-SHARE COUNT NON-ZERO>,,<
Cause: The monitor is attempting to deassign a slot in the non-OFN
part of the SPT tables. The caller is expected to have ensured
that the SPT slot is no longer in use. The BUGHLT indicates
that the share count for the SPT slot is non-zero, indicating
that some process is using the slot.
>)
DEFBUG(HLT,SHROFD,PAGEM,SOFT,<DWNSHR-OFN SHARE COUNT UNDERFLOW>,,<
Cause: A routine has been called to decrement the share count for
an OFN. The BUGHLT indicates that the count was already 0.
>)
DEFBUG(HLT,SHROFN,PAGEM,SOFT,<UPSHR-OFN SHARE COUNT OVERFLOW>,,<
Cause: The share count for an OFN has been incremented beyond the
maximum value. It should not be possible for a user program
to cause this.

Cause: This BUG is not documented yet.
Action:
>)
DEFBUG(HLT,SKDMPE,APRSRV,HARD,<MPE IN SCHEDULER OR PI CONTEXT>,,<
Cause: A page fault occurred indicating an AR or ARX parity error
while the monitor was processing an interrupt or running
the scheduler. This BUGHLT occurs regardless of whether the
error is repeated when the reference is retried or not.
The monitor has printed a description of the problem on the CTY.
A SYSERR block has been created and will be placed in the
SYSERR file when the monitor is rebooted.
>)
DEFBUG(HLT,SKDPF1,APRSRV,SOFT,<PAGE FAIL IN SCHED CONTEXT>,,<
Cause: A page fault occurred while the monitor was running in scheduler
context, and the page fail word did not indicate a hard
failure. This is probably a software bug because the
scheduler executes only resident code.
One cause of this failure is a reference to a piece of swappable
code or data that is not currently in memory. The flags and
PC are in TRAPFL and TRAPPC; UPTPFW contains the page fail word.
>)
DEFBUG(HLT,SKDTRP,SCHED,HARD,<INSTRUCTION TRAP WHILE IN SCHEDULER>,,<
Cause: This BUG is not documented yet.
Action:
>)
DEFBUG(HLT,SMNOFR,APRSRV,soft,<NO FREE SPACE FOR SM10 VECTORS>,,<
Cause: The monitor called ASGRES to obtain some free space
for the unibus adaptor windows. ASGRES gave a failure return,
which supposedly means there's no free space left. This is strange
since UNBINI, which is calling ASGRES, is only called from SYSLD1 once
per unibus adaptor
during system startup, and hence free space shouldn't be used up yet.
>)
DEFBUG(CHK,SNPIC,JSYSA,SOFT,<SNPFN3: INSTRUCTION BEING REPLACED HAS CHANGED>,,<
Cause: This BUG is not documented yet.
Action:
>)
DEFBUG(CHK,SNPLKF,JSYSA,SOFT,<SNPFN0: CANNOT LOCK DOWN PAGE INTO MONITOR>,,<
Cause: The .SNPLC function of the SNOOP JSYS was trying to lock pages
from the user address space into the monitor address space.
It called the SETIOP routine in PAGEM to do this, and SETIOP
returned +1 indicating failure.
>)
DEFBUG(CHK,SNPODB,JSYSA,SOFT,<SNPF4C: COUNT OF INSERTED BREAK POINTS OVERLY DECREMENTED>,,<
Cause: The .SNPRB function of the SNOOP JSYS was removing breakpoints,
and the number of breakpoints in the linked list was greater
than the breakpoint count.
>)
DEFBUG(CHK,SNPUNL,JSYSA,SOFT,<SNPF5A: CANNOT UNLOCK SNOOP PAGE>,,<
Cause: The .SNPUL function of the SNOOP JSYS received a failure
return from the SETIOP routine in PAGEM while trying to unlock
a page that was locked with the .SNPLC function.
>)
DEFBUG(HLT,SPTFL1,PAGEM,SOFT,<SPT COMPLETELY FULL>,,<
Cause: The monitor is attempting to assign to a process a slot in the
non-OFN part of the SPT tables. Normally a linked list points to
the free slots. The header is now 0, indicating either that there
is confusion in the list or there is not available slot. The
monitor normally protects aginst this event by refusing to
assign additional SPT slots when the available number falls
below a fixed minimum. This BUGHLT indicates a failure of
this mechianism or corruption of the free list.
>)
DEFBUG(HLT,SPTFL2,PAGEM,SOFT,<SPT COMPLETELY FULL>,,<
Cause: A routine has been called to change the map for a page of a
process. The page is being mapped to a file pge that is not
already shared. The code is going to create an entry for the
file page in the SPT so that the destination can have a
share pointer. The Choice of a share pointer over an indirect
pointer was made because the count of available SPT slots
exceeded a threshold. The BUGHLT occurred because the head
of the queue of free SPT slots contains a zero, indicating
that there are no free slots. This means that there is an
inconsistency in the monitor's data.
>)
DEFBUG(HLT,SPTPIC,PAGEM,SOFT,<SWPIN - SPT PAGE ALREADY IN CORE>,,<
Cause: A routine has been called to swap a page into core. The id for
the page indicates that it is a page table. The BUGHLT
occurred because the SPT
entry for that page table already contains a core address.
>)
DEFBUG(HLT,SPTSHR,PAGEM,SOFT,<UPSHR-SPT SHARE COUNT OVERFLOW>,,<
Cause: The share count for an SPT slot (not an OFN) has been
incremented beyond the maximum value. This can be caused
by a pathological program.
>)
DEFBUG(CHK,SPWRFL,APRSRV,HARD,<SPURIOUS POWER FAIL INDICATION>,,<
Cause: A power-fail indication was given, and the monitor has
executed its sequence for an orderly power-down. The machine
is still running after a long delay, so the monitor has
declared the power-fail warning to be a mistake. The system
will restart as if power had failed.

Cause: This BUG is not documented yet.
Action:
>)
DEFBUG(HLT,STKOVF,APRSRV,SOFT,<MONITOR STACK OVERFLOW>,,<
Cause: The monitor's stack overflowed when it entered a common routine
used for creating temporary storage. This routine adds a
quantity to P and then executes a manual check
for stack overflow, so it does not go through the normal
hardware stack fault logic.
>)
DEFBUG(HLT,STRBAD,PAGEM,SOFT,<ASOFN-ILLEGAL STRUCTURE NUMBER>,,<
Cause: A routine has been called to assign an OFN (index block). The
caller provided a structure number that was invalid, either
because that number can never exist or because it does not
exist now.
>)
DEFBUG(HLT,STRTER,MEXEC,soft,<FATAL ERROR WHILE PROCESSING PREVIOUS STARTUP ERROR>,,<
Cause: When a software channel 34 or 35 interrupt happens on fork
0, the monitor transfers to the code specified in the right half
of MONBK. This address will often be JB0INT. JB0INT handles errors
in fork 0. While JB0INT is doing its error recovery, it sets MONBK
to J0EMER, so that this STRTER bughlt will occur if
another error happens during JB0INT.
>)
DEFBUG(HLT,STZERO,FILINI,HARD,<FILINI: STRTAB ENTRY FOR PS IS 0>,,<
Cause: This will happen if the code that is supposed to set up
the STRTAB entry for PS somehow never got executed. This should
never happen.

as well.

DEFBUG(HLT,TTICN0,TTYSRV,SOFT,<TCI - NO BUFFER POINTER BUT COUNT NON-0>,,<
Cause: At TCI0 (get a character from the line's input buffer) the pointer to
the dynamic data base for the line was 0. This could either be a
coding error or the resident table containing the pointers was
clobbered.
Action: Look at the dump. The stack should indicate which routine called
TCI0 without the pointer.

DEFBUG(HLT,TTOCN0,TTYSRV,SOFT,<TTSTO - NO BUFFER BUT COUNT NON-0>,,<
Cause: At TTSTO5 (get a character from the line's output buffer) the
pointer to the line's data base was 0. This could either be a coding
error or the resident table containing the pointers has been
clobbered.
Action: Look at the dump. The stack should indicate which routine made
the call without a pointer.

DEFBUG(HLT,TTONOB,TTYSRV,SOFT,<TTY OUTPUT - NO BUFFER BUT COUNT NON-0>,,<
Cause: At TTSND7 (send a character to a line) the pointer to the
line's data base was 0. This is either a coding error or the resident
table containing the pointers was clobbered.
Action: Look at the dump. The stack should indicate which routine
made the call without a pointer.

DEFBUG(HLT,UIONIR,PHYSIO,HARD,<UDSKIO - NO IORB FOR NOSKED FORK>,,<
Cause: The routine UDSKIO was called to do special IO for a fork,
and to do the IO it uses one of a group of preallocated IORBs.
But there were no free IORBS left, and the fork could not
block because it was NOSKED.

DEFBUG(HLT,UNPGF1,APRSRV,HARD,<MEMPAR-PARITY ERROR DURING MEM SCAN>,,<
Cause: A page fault occurred while the monitor was scanning memory
looking for an MB parity error. The monitor expects to cause
such a fault when it references the bad word in memory. However,
the PC indicates that the error occurred somewhere other than
in the instruction that is expected to fail.
The monitor
has printed a description of the problem on the CTY. A SYSERR
block has been created and will be placed in the SYSERR file
when the monitor is rebooted.
If the memory scan has detected any errors, the monitor has
printed a escription of them on the CTY, too.
>)
DEFBUG(HLT,UNPGF2,APRSRV,HARD,<UNKNOWN PAGE FAILURE TYPE>,,<
Cause: A page fault has occurred and the page fail word indicates
a "hard" ERROR. The monitor has read the type of failure from
the page fail word and one of the following is true:
1. The hardware is never supposed to generate the code.
2. The code is valid, but the scheduler is running, and this
code should never be generated from scheduler context.

DEFBUG(HLT,UNXMPE,APRSRV,HARD,<PFCDPE-UNEXPECTED PARITY ERROR TRAP>,,<
Cause: The monitor was processing an AR or ARX parity error when
a second error occurred. The monitor retries the reference
that caused the original error and is prepared to handle
a second error. However, the BUGHLT indicates that the
error occurred during the processing but not during the retry.

Cause: This BUG is not documented yet.
Action:
>)
DEFBUG(HLT,UXXCKP,MEXEC,soft,<COULDN'T CREATE CHECKPOINT FILE>,,<
Cause: The file PS:[ACCOUNTS]CHECKPOINT.BIN.1 could not be referenced
for one reason or another. The code first attempts a GTJFN (GJ%PHY,
GJ%OLD) and an OPENF (OF%RD,OF%WR,OF%RTD), one of which must fail
for UXXCKP to be a possibility.
After the above GTJFN or OPENF has failed, then a GTJFN (GJ%PHY,GJ%NEW)
is attempted. If this succeeds, then UXXCKP will occur if a failure
happens on one of the following: the subsequent OPENF (OF%WR,OF%RD),
the call to ASGSWP to allocate CKPSIZ words, or the SOUT writing
CKPSIZ words to the checkpoint file.
If the GTJFN (GJ%PHY,GJ%NEW) fails, then another GTJFN (GJ%PHY,GJ%DEL)
is attempted, and its failure will cause UXXCKP. If this GTJFN
succeeds, however, then a CHFDB (turning off FB%DEL to undelete the
file) is done, and its failure will also cause UXXCKP.
Action: Bring up the system without the checkpoint file being referenced.
(Sorry, I don't know offhand how to do that.) Then, get the
checkpoint file into a state such that none of the above failures
will occur.

DEFBUG(HLT,UXXCRE,MEXEC,soft,<CANNOT CREATE USAGE FILE>,,<
Cause: If the GTJFN (GJ%PHY,GJ%OLD) or the OPENF (OF%RD,OF%WR,
OF%RTD) on the file pointed to by CKPFIL (PS:[ACCOUNTS]
CHECKPOINT.BIN.1) fails, then another GTJFN (GJ%FOU) and OPENF
(OF%WR) is attempted in order to create a new chkecpoint file.
If these latter GTJFN and OPENFs fail, the UXXCRE bughlt occcurs.
Action: Analyze the error code from the failing jsys, and fix the
checkpoint file so that the error doesn't happen.

DEFBUG(HLT,UXXILL,MEXEC,soft,<USGMES: ILLEGAL FUNCTION CODE>,,<
Cause: The USAGE jsys causes entries in the usage queue. Each
entry has a dispatch offset which is used by USGMES as an index into
a vector for calling the appropriate support routine.
If the dispatch offset is tooo large, this bughlt occurs. Since the
monitor itself is creating the entries in the queue, such a mismatch
should never occur.
>)
DEFBUG(HLT,UXXMAP,MEXEC,soft,<USGMAP: CALL TO JFNOFN FAILED>,,<
Cause: USGMAP wants to map a page of a file into FPG0 via SETMPG.
It calls JFNOFN to convert the jfn.pn atom to ofn.pn, which SETMPG
wants. If JFNOFN fails, this bughlt occurs. Some reasons that JFNOFN will
fail are: jfn is not associated with a disk file, jfn is not open,
attempt to create new page table but file not open for writing,
attempt to create new page table for a directory file, attempt to
create new page table but there's no room on disk.
>)
DEFBUG(HLT,UXXOPN,MEXEC,soft,<UNABLE TO OPEN USAGE FILE>,,<
Cause: USGINI's OPENF (OF%RD,OF%WR,OF%RTD) failed to open the
file pointed to by USGFIL, probably PS:[ACCOUNTS]SYSTEM-DATA.BIN.

DEFBUG(HLT,XSCORE,PAGEM,SOFT,<CST TOO SMALL FOR PHYSICAL CORE PRESENT>,,<
Cause: A routine has been called to map a specified core page to a
specified virtual page. The BUGHLT indicates that the caller
provided a page number of a core page that does not exist
(i.e., it is too large). This BUGHLT can occur if a monitor
that is built for less than 256K is booted on a machine whose
memory exceeds 256K.
Action: If the monitor was built for less than 256K, and there
is more than 256K of memory on the system, rebuild the monitor
for the correct amount of memory.
