typically whenever system crash occours, I see running a batch which
starts an alarm setting command procedure by user account MCC_MANAGER.
The DCL command $ SHOW PROC/CONT shows a process in MUTEX state and
continuous deplention of BYTLM quota.
Increase BYTLM doesn't fix the problem but I suspect that behaviour has
some connection with system crash because if the alarm setting command
procedure doesn't start system crashes don't occur.
THANKs in advance
Pino.

| 5444.1 | MCC exception? | GLDOA::DSMITH | Fri Aug 06 1993 12:01 | 8 | |
I have seen a similar crash footprint in the middle of a batch job doing a large number of historical mcc>sho snmp entity tot utilization commands. The process had a Kernel mode AST (QIO) outstanding. I can't see how MCC could cause a crash, though. Does MCC have any code running that could generate an exception in kernel mode? Doug | |||||
