[rhn-users] RedHat AS2.1 locks up during backups

[Lamon, Frank III]

We're having a problem with RedHat AS2.1 servers (Dell 2650s) locking up
during backups with Veritas Netbackup. The boxes become completely
unresponsive and have to be power cycled to bring them back up. This
only happens during backups and the server gives no warnings/alerts or
info in the messages files about what happened - just looks like the
server was running fine and then stops cold until power cycled. It looks
like the server is running out of processes/threads/open somethings - we
can't figure it out (we thought maybe it was caused by some locked
files, but we have Netbackup skipping locked files now and the crashes
continue). Any help or insight (like where else to look for clues to the
cause) would be appreciated.  

Thanks,
Frank LaMon
