Segmentation faults on map changes

[disjunto]

I'm getting segmentation faults on my server at map changes and game starts (seems to be on round_start)

Os: Debian Lenny 64bit
CPU: Q6700 (I think(
RAM: 4gb
Game: left4dead2
Addons: Occurs both with and without addons (sm,mm)
Startline:

Code:

screen -dmS l4d2_2 ./srcds_run +clientport 27006+## +hostport 27016+## +exec server##.cfg +ip **** -steamport 27691+## -fork 4 -game left4dead2 -debug
OR
./srcds_run -game left4dead2 -port 27016 -debug

Have completely removed installation, redownloaded hldsupdatetool, created new user acount, run under root, reduced from fork to single server and closed all other servers.

Code:
