great !

the problem you mention is what you wrote in a former msg, right:

that is really strange, I do not have such problems at all and it seems we are 
running basicly the same system, AV8 + X2 + releng_6.

so the gameserver needs linux_compat? I haven't it compiled in my kernel but 
on some parent caches which talk udp between them and some loaded DNS servers 
I got ocasionally udp errors but I could get around it by setting 

net.inet.udp.recvspace
net.inet.udp.maxdgram

to higher values.
