I think you may be needing to use QSUBHOST in torque.cfg on your
submission server.  I have this in my /var/spool/torque/torque.cfg:

    QSUBHOST betsy3-e1.fda.gov

I've also been getting quite wound up with problems between hostnames
and interface names on multihomed systems.  I'm also seeing issues
between short names and fully qualified names.  The documentation does
not seem very clear about this.

I would like to see some guidance/best practice on host/interface
naming for a basic cluster.  My clusters have the compute nodes single
homed on private networks with login/head nodes dual homed.
