Tux still unstable



Hello,

After a bit of testing the latest tux (2.6.18.1) with the tux-3.2.21 I came
again to the conclusion that we cannot run tux on our production servers. I
tried running tux from time to time before, starting when it was still
running on 2.4 etc.
The first testing went fine, it gave me my images, it send everything else
to apache. One user browsing the website is going very well, and it doesn't
bug onder two clients trying to get 1.000.000 images as fast as possible.

So I put the server back in the webpool and had three kernel panics:

1 - I forgot to turn of logging (debugging was off already) and tus crashed
withing two seconds after getting requests 'from the net'

So I rebooted, turned off logging, restarted tux

2 - I decided to see for one second what tux was doing, so I did a "echo 1 >
/proc/sys/net/tux/logging && sleep 1 && echo 0 > /proc/sys/net/tux/logging".
Two seconds after this tux crashed again with a kernel panic and an
unreacable site.

3 - Well, so I rebooted and stayed far away from the logging facility. After
around 3 minutes of serving nonstop images tux decided to crash again with a
kernel panic.

So tux is exit for me, but I probably try it again after some development
has been done.

Ps, the third kernel panic:
