Hi all!
I had to reboot eskimo twice during the last days. Today, after the second
time I rebooted, I decided to investigate and see what caused the problem. So
I found the messages like that in /var/log/messages:

Googling "oom-killer":
http://www.google.com/search?q=oom-killer&ie=UTF-8&oe=UTF-8
I see that it has to do with killing processes that occupy memory once the
system runs out of such.
top after the reboot showed that the RAM was filled in almost entirely, while
the swap was empty. Heavy memory occupiers were the apache processes, sympa
and mysqld.
What should we do about it?
Sympa is the only new addition on the server, right ? Can you move the
lists to beak ? It takes ~20% of memory.
The load on the apache might come from the move of the mandriva mirror.
I also suspect rsync to create peaks in memory usage while syncing.
