kernel oops under heavy load

Hi,
My answer comes a little bit late because I was testing the stability with
respect to load as well to long-term behavior. It seems to work now. The
reason might be that I had some trouble with the afs-cache. It is long enough
(2GB). It is an ext2-system but arla resides on reiserfs. Now it uses
exclusively ext2, and it works... Looks like I have some stale config files
from my many attempts.
Thanks a lot
Michael
