You have too many resources_min/max/default set.  It is confusing the scheduler.

unset queue long resources_max.cput
unset queue long resources_max.ncpus
unset queue long resources_max.nodes
unset queue long resources_min.cput

unset server resources_available.nodect
unset server resources_default.cput
unset server resources_default.nodect

And restart pbs_server.


"nodes" is a string, min/max.nodes is meaningless.
"nodect" is an integer computed from nodes, default.nodect is meaningless.

"cput" is largely unreliable unless you can enforce that all processes are
children of pbs_mom.  "walltime" works well for all cases.

"ncpus" can't be used with "nodes" because they are contradictory.
