Problems running hlds (Halflife)

[michael]

Hello,

I get the following messages when running and trying to connect to the Halflife server:

May 18 23:40:56 spring kernel: UDP: bad checksum. From 68.82.64.18:3583 to 213.133.100.139:27015 ulen 19

What is RLIMIT_CORE? Has anyone an idea howto solve that problem?
Im using kernel version 2.4.20 with grsecurity 1.99e patch.

Bye,

this looks like a NULL (function) pointer dereference or something similar and hence an application bug.

RLIMIT_CORE is a resource limit that controls coredumping. try 'ulimit -c' in a shell and you'll see what it's set to by default on your system (a 0 means that core file dumping is turned off). as for fixing the problem, someone will have to debug the code to see where/why the NULL dereference occurs, you should probably contact the author of engine_amd.so.
