Hi Richard, I would like to double check the following items if I were you.
1. /etc/hosts, ssh keys, nagios/nrpe, gmetad/gmond are all synced through all
the nodes.
2. Make sure that the root user can ssh into all the nodes back and forth
without password.
3. All the daemons of the job submission are running on all the nodes:
(torque-server, torque-mom in the head node and torque-mom in the client
nodes and maui on the head node)
I assume that you are using torque as RM and maui as a scheduler.
Regards,
