Hi list,

I have an old 486 box with 28Mb ram and four 3c509 NICs for a home
firewall. Today I found it locked up and after reboot discovered some
oopsen in logs:

Kernel is vanilla 2.4.3. Distribution is RedHat 7.0 and the time it
occured is just when redhat runs its bunch of stuff from cron scripts. I
can provide additional info if needed.
I don't belive it's a ram problem, because the box has been runnning
flawlesslly for more than half a year now.

Please cc me in replies.
