Researching the logs for suspicious processes I found on both crashes a 
MailScanner process "kernel: Out of Memory: Killed process 2121 
(MailScanner)." In the first crash the process had been running for about 4 
hours, in the second crash it was about 12 hours. I changed "Restart Every" 
to hourly restarts. (Usually I restart every 24 hours without having 

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 
asign this problem to bad memory or a kernel bug? Searching the net I find 
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 
MailScanner process first. (As this is only a mailserver its not a big 
suprise that MailScanner ist the first one to die, there is not much more 

Cahnging the value in "Restart Every" hopefully helps, but isn't it a 
workaround for other problems?

Thanks for your opinion
