If you have swamped machines frequently, we need to know
about it. I had understood the original reporter in a way
that kill -9 really does not kill the processes which even
under load after a while should get rid of processes.

And my experience is that CPU load is a lot easier to handle
than memory over load where the machine swaps like mad.

Sorry for the misunderstanding,
