system panic

[Vlad]

Hi!

Last few days I have this problem with my system. Is there any ideas about it?
Can it be a hardware problem?

I have serial console configured on this host, but same happen with
general (keyboard/screen) console only.

There are problems with httpd (php scripts), but this kind of problems should not kill the server.


Thank you.
