Cause: A "set CI offline" has been requested and SCA refuses to close a CFS
connection. The call to SC.DIS to disconnect from the remote node
failed. This may result in a CFRECN BUGHLT when the CI is put on-line.
Action: It is unlikely that this can be caused by a software problem. Field
Service should run diagnostics on the CI20. Field Service should make
sure that you have up to date hardware (most recent link boards) in
your CI20. If this problem is reproducible, set this BUGCHK dumpable
and send in an SPR along with the dump and instructions on reproducing
