If a pbs job is unable to write to disk (usually a log file to the user’s home area), check the file /var/spool/torque/mom_priv/config and make sure that there’s a line for each SUBMISSION system that looks like this:
$usecp uct3-edge3.uchicago.edu:/ / $usecp uct3-edge5.uchicago.edu:/ / $usecp uct3-edge7.uchicago.edu:/ /
Then, if any changes were made to this file, restart pbs_mom.
