Hi,
Note: For any replies please send a copy to me :) as I'm not subcribed to
the list.
This is an oops I've got today - the machine kept running fine but oopses
still shoudn't happen IMO. The kernel apparently oopsed when running
webalizer (webalizer.com). I've never seen this before though.
ksymoops 2.4.0 on i686 2.4.9. Options used
-v ./vmlinux (specified)
-k /proc/ksyms (default)
-l /proc/modules (default)

In 'dmesg' there are also quite a lot of these messages:
swap_free: Trying to free nonexistent swap-page
swap_free: Trying to free nonexistent swap-page
I don't know if these problems are related but I haven't got such errors on
any other machines...

I've attached the .config file for this machine's kernel too.
Another interesting point is that this happened after 27 days of uptime so
this might give you another hint. I haven't had any problems before.
Is this a known error or am I the first _lucky_ guy to report this? :)
Thanks,
Gernot
