[Tony Schreiner]

On a cluster of 62 nodes, with torque 2.1.10 and maui 3.2.6p19

overnight 2 nodes have stopped accepting jobs

there are jobs in the queue and get submitted to other nodes but not  
to node42 and node44.
node40 and node41 are not eligible for the queue being run so it's ok  
that they have no jobs.

Please note the last column on those 2 nodes which is the "tasks"  
parameter and is non-zero

I have restarted pbs_mom on the nodes, also done  momctl -C and momctl  
-c all on those nodes.
There is nothing in the mom_priv directory associated with any job.

Thanks
