Restart pbs due to submitting too many jobs

Hi,

Please check the below

  1. pbs_server service is up and running
  2. strace the qstat command to find out the reason
  3. firewall, selinux, DNS are all intact and not down
  4. check the pbs server logs

Please refer
Pbsnodes: cannot connect to server , error=111 and Failed to start PBS dataservice

Thank you
