Qsub -I no longer works

I can submit a job using a script, but if I try and run an interactive job, it just hangs. The system is free, no other jobs are running, so it is not a matter of resources. Just hangs and never produces a prompt. What should I check for? Thanks.

Please check:

  1. DNS issues (forward and reverse address resolution)
  2. firewall
  3. SELinux

Please browse this discussion: Interactive Job errors out with 'apparently deleted'

Well, a co-worker discovered the problem and offlined compute-0-0. Doesn’t explain why we could submit a job and it would run, but not perform an interactive job. Thanks.
