Hello


I'm trying to enable preemption under maui/torque.  My software versions 
are maui-3.2.6p14-3 and torque-2.1.5-1.  I have two queues defined under 
maui, short.q and extrashort.q. Any jobs submitted to extrashort.q 
should cause short.q jobs to be suspended.  I have made some progress 
however I'm getting the following error messages in my maui.log file -

My maui.cfg file looks like this -

Anyone have any ideas or a maui.cfg file that implements preemption?
