     Thank you again for your consideration of these issues. We're finding
that the most frequent errors appear to be 15001, 15004 and 15041. It may
be useful for us to send our logs to you -- at the momemt that is difficult
to sort out since I'm at home, and so remote from the nodes. Thanks for the
offer to investogate the problems further.

On the level of prevention could I please broach the following questions to
you, and torque-users...

I see that errors 15001, and 15004 appear to be cleared following a restart
of the mom. My initial thought was to try to keep the slate as clear as
possible by perhaps restarting the mom following each job. Does this make
any valid sense, and would doing such a thing potentially cause any issues
in the system? It's interesting that the error appears to be random,
however annoyingly does seem to cause jobs to queue up at the problem node.

Error 15041 is very problematic. A closer investigation shows that multiple
instances of jobs appear to run on the system. Briefly jobA trys to run on
nodeX. nodeX, however reports 15041 and the job is sent elsewhere. The job
then starts to run on nodeY. Unfortunately despite the rejection of the job
on nodeX -- it does in fact run on that nodeX as well... With respect to
addressing this issue would you recommend upgrading to 1.1.0pX where X is
either 3 or 4?

Finally would an upgrade help to eliminate errors 15001 and 15004? What is
the theory and the experience of the community, please.

Thank you again -- David.
