computational nodes went down when job was submitted

[caicairay]

The computational node will lose connection after some specific job (request 20 nodes) was assigned. The assigned job was rejected and re-queue many times and BatchHold in the end.

Possible configuration reason:
It should be mu01 in /var/lib/torque/server_name, but localhost was found.

Need to reconfigure after nodes back online.

The pbs daemon config is in

 ~]# cat /var/lib/torque/mom_priv/config
# Configuration for pbs_mom.
