I'm using 2.4.8. Thanks for the feedback.

Thanks, but that didn't really work. It killed the pbs_server process, and
I was able to restart it, but even though I am using the 75 cores I have
available (still missing those couple extra cores I tried to allocate
earlier), it shows me some nodes have free processors when they clearly
don't:
% qnodes -l all
udesktop267.wacker free
userver133.wacker free
userver211.wacker free
userver209.wacker job-exclusive
us306.wacker job-exclusive
us254.wacker job-exclusive
userver121.wacker job-exclusive
us323.wacker job-exclusive
udesktop264.wacker free
% sudo cat /var/spool/torque/server_priv/nodes
udesktop267.wacker np=4
userver133.wacker np=4
userver211.wacker np=8
userver209.wacker np=8
us306.wacker np=12
us254.wacker np=24
userver121.wacker np=4
us323.wacker np=12
udesktop264.wacker np=4
% qwhere
2 udesktop264
1 udesktop267
24 us254
12 us306
12 us323
4 userver121
4 userver133
8 userver209
8 userver211
The qwhere command is a simple bash function:
qwhere ()
{
qstat -1n | egrep ' R ' | awk '{print $12}' | sort | uniq -c
}
Does the state of a node possibly not get updated until a job completes on
it?
