After restarting workstation, PBS was offline so I issued /etc/init.d/pbs restart. I got this error 'Restarting PBS

PBS Home directory /opt/pbs needs updating.  
Running /opt/pbs/libexec/pbs\_habitat to update it.

In case you haven’t fixed this yet, most likely the problem is that /etc/pbs.conf has a wrong value for PBS\_HOME. The usual setting is  
`PBS_HOME=/var/spool/pbs`  
It appears you have it set to /opt/pbs, which is usually the value for PBS\_EXEC.

Still haven’t fixed. My PBS\_HOME is in /var/spool/pbs only. Here is the /etc/pbs.conf file

cat /etc/pbs.conf  
PBS\_SERVER=benq  
PBS\_START\_SERVER=1  
PBS\_START\_SCHED=1  
PBS\_START\_COMM=1  
PBS\_START\_MOM=1  
PBS\_EXEC=/opt/pbs  
PBS\_HOME=/var/spool/pbs  
PBS\_CORE\_LIMIT=unlimited  
PBS\_SCP=/bin/scp
