A while back (~4-5 yrs) Chris Torek (I think) produced a nice little
patch to the 4.3 kernel to kill groups of run away (and rapidly
spawning) processes - this was the 'zonk' system call. You could probably
gain an insight into your problem by looking at this. The catch is that
I don't have access to the machine that I installed the patch on.
Zonk was very useful, especially on Student/teaching machines - one could
guarantee that some bright spark would experiement with self spawining
processes, zonk would kill all jobs owned by a particular UID stone dead.
