The job engine service stops running without logging an event and all traces
of the job that was active when the job engine stopped are removed from the
BEX management console.

This happens with one job which is backing up data on the backup server itself
- it's a job we run once a week. It is a file server, no Exchange installed.

What I've done to troubleshoot this:
Upgrade from 8.5 to 8.6
Recreate the backup job
I've scoured Veritas' knowledgebase to no avail
The server has plenty of resources available

Other interesting fact:
Once I've restarted the job engine service and I rerun the failed job, it
will complete the backup successfully. The job usually fails close to 100Gb,
but can be more or less.

If anyone has had a similar problem, or has any suggestions, I would be most
grateful. I'm getting tired of my pager waking me up when the job engine
stops in the middle of the night.

Thanks in advance for your assistance.
