Ratko, Moorthi and others,

We did implement wrappers for both qstat and qsub to work around the PBS
issues and replaced the default version during the maintenance.

Under normal conditions, the new wrappers are much more stable than the
original qsub and qstat. While as Ratko pointed out, there are massive
number of jobs submitted in the last couple of days, which makes the system
(especially the Moab/Torque) over-loaded. We are working with the vendor to
find a feasible way to prevent this from happening in the future.

The Zeus team has been working with the user to reduce the workload in the
last couple of days. We have observed the throughput of PBS in the last 24
hours has been improved significantly due to the reduced workload on the

I am running a previous version of NEMS regression test on Zeus this
morning. So far, 11 tests passed without any issue. Please give another try
to see if it is any better today.

Thanks for your patience.
