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:

Heavy memory occupiers were the apache processes, sympa and mysqld. What should we do about it?
