Could you please check these

1. SELinux is disabled and if you disable now restart the system
2. Firewall is disable or allows ports 15001 to 15009 and 17001
3. All the systems in the clusters should have static IP and hostname (DNS is resolvable) and /etc/hosts on all the systems are populated correctly and resemble the same
4. make sure the password-less SSH for all the users work without being asked for a password or hostkeychecking

- PBS Server to compute node
- Compute node to PBS Server
- Compute node(s) to Compute node(s)

Please check and share the server / scheduler / comm logs , the tail end of the logs should have some reason for exiting.

Please share your job submission script with information blocked out  
It seems there was an issue with permission executing the line 28, which is /home/pi/demo/fpi-serial

Hope this helps
