If we do a "qsub -I -X...." we can reproduce this but this doesn't appear to be how the user is running their job. Looking across our cluster as a whole we only see user owned pbs_mom's for this user - there appears to be a clear correlation between where this is happening and the root owned pbs_mom process at the top of the tree crashing.

Hmm, sorry, I just checked and the sub-mom still is owned by root.

Put this into your mom_priv/config
$logevent 0x1ff
$loglevel 7

Plus if you can use a debug build (the mom daemon will stay attached to
the terminal and output a lot of important information).
