Thanks Garrick,

I checked syslog and found the error message below:
Sep 12 08:05:21 node010 pbs_mom: No such file or directory (2) in 
TMomFinalizeChild, cannot open /usr/spool/PBS/aux/941.auriga.qut.edu.au

So I have created the directory '/usr/spool/PBS/aux' and I can now 
submit jobs.
I do not think to look in the syslog logs as I thought all the error 
were logging to the mom logs.
