Linux dedicated server crash when someone try to join it

[pfoo]

Hi !
I've got some problem with my new (and first) Killing floor linux dedicated server. I followed the howto on http://forums.tripwireinteractive.co...ad.php?t=30911
But when i try to join the server, the server crash while I am on the "connecting" screen.

I already tried to upgrade and reinstall the server many times.
The server doesn't have any firewall.

Here are launch and crash logs :

Any idea on what's going on ?

I finally got it working. The problem was related to pax (a linux kernel security patch).
If someone has the same problem, you just need to use paxctl on your ucc-bin-real file like this :

paxctl -c ucc-bin-real
paxctl -m ucc-bin-real

Hello. I have CentOS 4.6 system, not have paxctl here. Any solutions?
