When AutoSys misbehaves (out of misconfiguration or ....) it generates
thousands of processes that render a server unresponsive -its virtual memory
exhausted that the only way out of this would be to power off the machine.
On two occasions already, when the server came back up, we've a corrupted OS
disk:

02-Jun-2002 13:45:12 syncing file systems... done
02-Jun-2002 13:45:13 skipping system dump - no dump device configured
02-Jun-2002 13:45:13 rebooting...
02-Jun-2002 13:45:13 Resetting ...
A closer look at the faulty system disks indeed confirmed that we've a
corrupt /sbin/init file plus a host of other files that the only would be to
do a full system restore of the OS backups.
Questions:
- Has any one experienced this at their sites?
- How possible is it that a system that had its processing limit exhausted
corrupts the system? Or is this as a result of not gracefully shutting down
the system?
Thanks and I will summarize.
