Random hlds crashes. Exploit?

sparkey · **Author**

Recently many of my servers started crashing randomly. I'm guessing it's an exploit cause nothing has been changed and i always update hlds manually.

Is there a new known exploit that can be fixed?

This is the logs i can find but nothing useful.

I don't think that's a exploit.
Try to install metamod-p or to disable metamod and run the clean server for some time.
Maybe some plugin or module is bugging your server. Metamod-P solved my problem on CentOS 5.5.

Best Regards!

Thanks for your answer, i will try with metamod-p and get back

Just strange that it started just now and i have never experienced this before.

sparkey · 07-16-2011 , 11:06 Re: Random hlds crashes. Exploit?

metamod-p did not solve the problem, only using one plugin with the following modules.

Code:

[ 1] MySQL                   1.8.1.3746  AMX Mod X Dev Team   running    
[ 2] Engine                  1.8.1.3746  AMX Mod X Dev Team   running    
[ 3] CStrike                 1.8.1.3746  AMX Mod X Dev Team   running    
[ 4] CSX                     1.8.1.3746  AMX Mod X Dev Team   running    
[ 5] Sockets                 1.8.1.3746  HLSW Dev Team        running

I should say that you probably need to try the latest update (5369). I had same issues and now its working fine after the update.

./steam -command update -game cstrike -beta hlbeta -dir .
