Hi Carlos:

I've seen my server boxes print "Unable to load interpreter" too much
times.
Also several important processes (httpd, sendmail, etc) stoped and could
not spawn aditional processes.

OOM Killer is not the solution for everyithing, but I have a lot of bad
experiencies to tell with servers trashing to dead and stoping important
services.

I can crash my machine (2.1.124, 64MB RAM, 44MB Swap) with that little
program and would be very happy having a few services stoped but the
machine alive.

Also Rik does some heuristic to do not kill processes with direct
hardware access (eg, X) and things like that...

Regards

Dino
