Yes, I am seeing the same thing here with my two instances of torque.

With torque-2.5.7
# lsof -i -n -P|grep pbs
pbs_serve 32368     root    8u  IPv4 242454945      0t0  TCP *:15001 (LISTEN)
pbs_serve 32368     root    9u  IPv4 242454946      0t0  UDP *:15001
pbs_serve 32368     root   10u  IPv4 242454947      0t0  UDP *:1023

with torque-4.0.1 from torque-4.0.1.snap201204276052.tar.gz
]#  lsof -i -n -P|grep pbs
pbs_serve  2553     root    7u  IPv4   14851      0t0  TCP *:63000 (LISTEN)
pbs_serve  2553     root    8u  IPv4   14853      0t0  TCP 192.168.8.27:15001 (LISTEN)
pbs_serve  2553     root   11u  IPv4 2592331      0t0  TCP 192.168.8.27:15001->192.168.8.27:39678 (ESTABLISHED)

On v3 and earlier pbs_server would listen to all interfaces per default, but this seems to have changed under v4.

Version 3.0.2
# lsof -i | grep pbs
pbs_serve 17765    root    8u  IPv4 383811137       TCP *:15001 (LISTEN)
pbs_serve 17765    root   10u  IPv4 383811140       UDP *:15001 
pbs_serve 17765    root   11u  IPv4 383811141       UDP *:1023 

Version 4.0.1 (snapshot)
[root at hpc1 torque]# lsof -i | grep pbs
pbs_serve 21247    root    7u  IPv4 14268817      0t0  TCP *:63000 (LISTEN)
pbs_serve 21247    root    8u  IPv4 14268819      0t0  TCP hpc1.cc.uit.no:15001 (LISTEN)
[root at hpc1 torque]# hostname
hpc1.cc.uit.no

under torque 4 pbs_server listen only to the interface associated with the hostname which makes it ignore all internal traffic thus compute nodes cannot contact it.  

Is it possble to get the old behaviour back?  Using the -H flag doesn't help as it breaks other things when communicating with the compute nodes.  The only way to get torque 4 functional was to set the frontend hostname to the same as the one on the internal interface, hpc1.local, which isn't a good solution.
