OpenPBS under RH7?

[Roger L. Smith]

Hello Folks,

We've got a pretty good sized Linux cluster that we are finally about to
release to our users.  During all of our testing and benchmarking, we've
been using RedHat 7.0 and the 2.4.2 kernel.  We've worked out most all of
the problems until we installed OpenPBS (v2.3.12).

Our test users have been experiencing a problem where the pbs_mom daemon
on the first node on a given job will die.  It typically seems to die
either when the job finishes, or when the user tries to qdel the job.
It's not consistent, however.  One of our users estimates that it fails 2
out of 5 times.  The corrective action for this includes deleting
everything out of /var/spool/PBS/mom_priv/jobs/<jobnum*> and restarting
the daemon on the node.

This is becoming a very serious issue for us, and may require that I
downgrade the entire cluster to RedHat 6.2 and/or a 2.2 kernel.  I'm not
anxious to do this for several reasons.

Is anyone on this list running a similar configuration, or have any
experience with this problem?
