As this is a brand new machine and I have two more installations with same O/S
and application versions running without any problems, I would like to get a
better idea of the reason for these crashes. Other posters on this thread

some posts on Spamassassin consuming memory. Anyhow I can see that the
machine stays fine for about one week, then it starts slightly to swap out.
And very fast and sudden it crashes with the OoM-killer, killing a
