thanks for your reply.
You are right, it sounds more or less like that. The difference is that the
kernel was running for quite a while without any problems and we are using a
different board (Intel server board S3210SHLX with Core2Duo CPU).
Being Saturday today it was possible to install the lasted Ubuntu server kernel
update 8.04.3 (Linux xxxxxx 2.6.24-24-server #1 SMP Tue Jun 30 21:03:25 UTC 2009
i686 GNU/Linux). I tried to reproduce the fail but with just me in the office
and no real traffic it's hard to do so.
Maybe it just helped. I will wait and see.
