I don't think it is a qsub issue. It looks more like a problem with shared 
memory management in MPICH. Google results suggest that you should run 
'ipcs' as root on the node to find out if there are any non-released 
shared memory segments. If needed, remove them manually with 'cleanipcs' 
or 'ipcrm'.
