[cobalt-users] [RAQ3] Strange log/messages

["Herby K" <mad1.z@xxxxxxx>]

Hi,

today our raq 3 was down for approx. 15 minutes (http was working but ssh
and mail not).
After that I checked /var/log/messages and these lines were at that time:

At 9:00 we could login and mail as usual. The serverload was 5.xx at that
time and CPU: User at 90% System 7%

Does anybody know whats going on here?
