this should do it. per definition if you have a zombie process
then you *must* have a parent since this is the one which got
not notified of the exit() of his child.Without seeing the complete
process list I can't tell. A restart of the parent mgd ( the one which
ends with -N in the process list ) doesn't restart the mgd's for each users
as they are all forked. So try to get all cli and corresponding mgd's
off the list and then it should work.

thanks
