I am using torque 4.0.1 on openSUSE 12.1 in a cluster environment. When I qsub a job (simple as "echo hello"), it remains in 'Q' state, and never gets scheduled. I can force the job to run with qrun, and it is executed on the first node without error.
I tried to find the solutions for the past few days but failed. I read the manual, the logs, even the source code, but still can not locate the problem. Of course I googled a lot, tried various solutions, however no one worked.
Here is some info that maybe helpful:
- pbs_sched is running, but its logs seem to suggest it receives no notification about jobs being queued.

- pbs_server log just showed that the job was queued into default queue batch:

The problem is that TCP Timeout is 0 seconds, which does not seem to be normal. During the diagnostics, the following log was found in mom_logs
05/13/2012 20:30:10;0001; pbs_mom;Svr;pbs_mom;LOG_ERROR::Resource temporarily unavailable (11) in tcp_read_proto_version, no protocol version number End of File (errno 2)
I googled it, but found nothing.
- I compiled OpenMPI with this torque 4.0.1 (for tm support), and I can mpirun test programs without any problem.
I hope someone can solve this problem. Thank you!
