Before I possibly go into a long explanation, I just want to double
check real quick... all of the processes in the job are children of
pbs_mom?  The jobs aren't using rsh/ssh to launch processes?

No, that means MOM had a problem sending one of the periodic node stat
messages.  Those messages don't contain job information.

As long as it doesn't happen all the time, it is fine.
