Pbs_server dies after starting

Hi,

I am trying to install openpbs by compiling from sources.
My OS is ubunut 18.0.4 running in a VM
It seems that after installation, all servers except the pbs_server comes up. I am unable to figure out what could be wrong.

root@vagrant:/# /etc/init.d/pbs status
pbs_server is not running
pbs_mom is pid 6532
pbs_sched is pid 6544
pbs_comm is 6522

It seems that the pbs_server starts and dies immediately afterwards. I can see that the pid is written to the server.lock file in /var/spool/pbs/server_priv directory. I see pid 6666 written to it. But if I were to look for the process associated with the pid, it is not there. ie ps -p 6666, it returns returns empty.

root@vagrant:/var/spool/pbs/server_logs# ps -p 6666
  PID TTY          TIME CMD

and here are the logs
