[Moabusers] Unable to handle kernel NULL pointer dereference

[James A. Peltier]

Hi All,

I received the following error on my head node this weekend and I'm 
unsure as to why?  I haven't really started digging into it too much 
yet, and thought I would just throw it out there to see what you all had 
to say.

OS: OpenSuse 10.0 i686
Torque: 2.1.8
Moab: 5.1.0p6
