I am testing a beta of a torque/maui "roll" for Rocks clustering 
software. This is supposed to be torque 4.2.2 and I run on CentOS 6.x. I 
seem to be having the same issues. Everything appears to be distributed 
to both of my test nodes (according to the maui logs) but all the work 
runs on one node?
