[Twisted-Python] strange server crash

This server crashed again today, again during maximum load for the day.
This time, no errors in the twisted log, and not even a segfault message in /var/log/messages : the pid simply ceased to exist.
Once again, this machine runs 8 twisted servers, but this one is slightly different from the others, and the error happened after the code for this server has been slightly modified.
I do not think this is the bad RAM anymore, because there's one particular server that keeps crashing on this machine.
