What does
ps -ef | grep pbs
return? You should see something like this:
... /usr/local/pbs/i686/sbin/pbs_server
if you see
... /usr/local/pbs/i686/sbin/pbs_mom -r
then the head node is also configured to run jobs.
also, check
# chkconfig --list | grep pbs
pbs_server 0:off 1:off 2:off 3:on 4:on 5:on 6:off
you should only see pbs_server on the head node. If you see pbs_mom,
then you need to turn it off and remove it
# chkconfig pbs_mom off
# chkconfig --del pbs_mom

Hi
I have torque pbs_server running on the headnode, which is also the
submit host. There are 32 other compute nodes, mentioned in /var/
spool/torque/server_priv/nodes file. There is a single queue at
present. Sometimes, mpi jobs requesting for 28/30 nodes, land up
running on the head node, though the head node is not a compute
node at all. netstat -anp shows several sockets being openend for
the job, and eventually the head node hangs up.
Appreciate any help/suggestion on this.
