Hi

I'm quite new to linux and have 4 identical server(hardware,suse 10.1). And they seem to freeze every few days randomly. The last entries in /var/log/messages is usually

I have run memtest for several hours without any problems. Also I ran seagate tools without any problems then I ran several scripts to push up load average and it ran fine for several hours. And then after I stopped these scripts it crashes.

I'm also running it in runlevel 3 so don't think it could be graphics card. Recently I recieve new problems in /var/log/messages

Oct 20 11:58:48 funnel03 kernel: eth0: link down.
Oct 20 11:58:50 funnel03 kernel: eth0: link up.

If someone knows what else I can check or do to find the root of this problem I would really appreciate it.

Thanks
