Hi,
i have a big problem with my Counter Strike Source Dedicated Server (no addons, just vanilla), the first few minutes the server runs at a CPU usage of ~ 35 % at 12 players but then the cpu usage increases rapidly to 97 % so it lags. I tried differend ways to solve this problem:
1. i looked at my server config (i use your standard config of the forums) nothing happend.
2. i looked at my logs of the server (-debug is on) everything seems to be ok.
3. the srcds_run autodetects my intel celeron 2.0 ghz and uses the i686 library so i tried to change it (-binary ./srcds_i486), but also with no effect on my problem.
4. i reinstalled steam and everything is upgraded -> nothing happend
i hope you can help me with my problem because i am helpless.

i have still the same problems
now i use the kernel 2.6.10
i tried my luck with cs 1.6 and hl1/2 deathmatch servers but always the same problem after a few minutes and over 7 - 8 players the cpu usage increases to 98 %. so ... is it a bug from the valve engines with my celeron ? because everything runs smooth before 2 months ... 
i still hope someone can help me
i don't want to reinstall everything :/

Same thing going on with me - I have the same kernel and a p4 3.06, and it's happening on other boxes of mine with a variety of CPUs.. Seems like it just started happening very recently - like within the last week or 2.
Let me know if you've had any luck resolving this.

cool, keep us posted! I'm wondering if it has to do with either the kernel or a recent update from steam. Thing is it seemed to just start happeneing since around the end of Jan or beginning of Feb.
I do have it running with a variety of kernels and it doesn't seem I'm having the same result everywhere.
I'm going to tar up an install that is particularly bad from one of my servers and put it on another box with an earlier kernel and see what happens. I'll let you know.
Also, are you running manimod?
and no - i'm an admin of joltservers dot com

yesterday i was at the data centre and i was shocked that my cpu fan was damaged or something like that, so i think my problem is that my cpu clock turns down after a certain temperature. So i repaired the cpu fan and tryed it again with 16 bots but the problem seems to be still alive because the cpu usage changes wild from 30 % to 97 % back to 50 % and so on ...
now i will try to check if my cpu is damaged or the cpu is still getting to high temps :/
are u also using debian ?
i will post more infos about my system

I'm using fedora core 3 - I'm going to tar and move one of the installs i'm having trouble with over to an FC2 box and see how it behaves.

Hi,
Same problem here, after 30 mins the cpu usage goes bananas between 25-80 % depending on the amount of players active (not death).
1 CPU P4 3,06
2 Gb mem
Fedora Core 3
1 thing it's running in SMP Multi processor mode due to the hyperthreating cpu, could this be the thing? Because in top i see 25% cpu usage and by the ./srcds it's double the amount.
1 more thing is the cashed memory, it's eating all the memory till there is left only 8mb, why cache? what is the point? maps ok but cache what players do etc. ?
Im rebooting the server during the night to free the memory. don't know what else to do?

I'm running that exact same setup - same cpu, same OS. I am starting to think it's the 2.6.9/2.6.10 kernels - as my FC2 and RH9 boxes seem ok.
I turned SMP/HT off on my box as well and had the same issue.
I think you're ok on the cached memory though, it's just kind of the way linux deals w/ RAM.

Well the CPU usage is increasing when the "free" memory becomes less and less.
Ive updated FD from core2 to core3 due to this problems but there is no difference.
