Re: processes still running after qdel

Thanks. I've used qdel -f in the past and it's very useful. Again, sorry
for not being more specific -- the issue I'm having is that after I use
qdel and can verify the job is no longer in the queue using qstat, the
process is still running when I login to the node and do ps -ef.

It could be that there is some problem with the process that causes it to
hang, but I would still expect that doing qdel would kill the process -- I
have to login to the nodes and kill them myself.
