Kernel Oops on Debian Etch

[Hugues Brunel]

Hello,

I use many (60) Dell Servers (from PE2650 to PE2950) with Debian Sarge, 
and now Etch. I have a problem with two PE860 DualCore (one on Sarge and 
one Etch).

Some time, a process crash with a Oops message. It arrives when load 
become a little high (but not very high). For exemple, it arrives some 
time when I compile a new kernel. And recently it arrives with MySQL 
server process.

It become very critical to me to correct this issue.

My kernel is Linux-2.6.19.

Here is the last message (this morning):

--------------------------------------------------------

I suspect a kernel bug but I don't find any information on google!??

Have you any idea to help me?

Regards,

Hugues Brunel.
