[torqueusers] No contact with server at hostaddr problem

I'm assuming the HWaddr (aka MAC) is the hostaddr just because
the hostaddr looks like a HWaddr. I'm not sure if this will help at

I had some problem before with Ganglia (not Torque): it was very
fussy about having the right interface configured for multicast.

The other thing that comes to mind is that the error message you
show mentions port 15001. Maybe you should check to see if
the node in question can talk to the server on that port. (It should
be able to since the other nodes can, I assume.) Log in on the
problem node, and try "telnet server 15001" and hit return once
the connection is made. You should see an error message.
