What are you using to schedule jobs? torque has a native fifo scheduler, but
you have to activate it. There are other schedulers available that torque 
can tie in with. Jobs won't run if the system scheduler isn't run and passing 
job start info to torque.

Try a manual qrun of the jobid to see if pbs will run. If the job runs, then the
issue you're seeing is probably a scheduling issue. If the job won't run, then
you should get an interesting error message to help with your troubleshooting.
