Hi All,
I have a problem with torque (openPBS) on x86_64 CentOS 5.2. Just to

The problem is that pbs_mom's child quits without giving any error logs.

I have asked torque users mailing list, but since the problem is
related strictly to CentOS 5.2 64bit, I thought I would go ahead and
ask here.
Any help is appreciated.
