We have a SMP cluster, and to avoid the death of innocent processes we use the
script in section "Cleanup of MPICH/PBS jobs" in
http://bellatrix.pcl.ox.ac.uk/%7Eben/pbs/

It doesn't always work, and some jobs are left lingering sometimes, but at least
it doesn't kill innocents (some day I hope I will have the time to look into it
and try to find out why).

Hope it helps. Cheers,
Angel de Vicente
