This means that something is wrong between pbs_server and pbs_mom.  I don't
think this has anything to do with maui.

Test with 'qrun'.  That is a torque command that will attempt to start the job.  If that also fails, then you really know it isn't maui.

Also, you are running trunk.  You should really start with the latest 2.1.x or
2.3.6 (releasing soon).

$clienthost is ancient.  You want to use $pbsserver.

And why use $restricted?  That disables security.
