(This post was last modified: 08-11-2010, 02:32 AM by wayner87.)
Just setup a dedicated server today, specs and info below:
BASIC INFO
Server OS: Ubuntu 10.4.1 LTS 32 bit
Processor: Intel P4 3.0 Ghz hyperthreaded
Ram: 1 GB
Game(s): Counter-Strike Source
Start Up Command: ./srcds_run -game cstrike -ip XXXXXXXXXXX -port 27015 -maxplayers 10 -tickrate 66 +fps_max 0 +map de_dust2 +exec server.cfg +tv_enable 1 +tv_maxclients 25 +tv_port 27020 -autoupdate&
Admin Mods: zBlock
Granted the server is really low spec but its cheap and im only running 1 gaming server (private match server for clan). The OS was installed today. Please note this also happened on another server with 2gb ram, dual core 2.2ghz on centos 5.5.
I notice that the memory leak happens when the server changes map, once i reboot the css server using "rcon exit" I get all memory back again. Sometimes I would be left with 16k left and 1 gb used for a 11 slot css server, this is the only application running on the server.
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
1240 server01 20 0 464m 367m 18m S 26 36.7 12:19.65 srcds_linux
The memory usage would go upto 60%. Anyone else having the same problem, is this a known issue?
Kind Regards,
Wayne

in the line presumably copied from top I see your server has 464 MB reserved memory. that is much indeed, but it could be right for some big maps and maybe with the enabled tv server (I don't know how much memory that takes). the question is, does the memory increase at every map change, even if you change back to the start map (dust2 in your case)?
I don't see any obvious mistakes why your server should have a memory leak. I also have zblock running on my match server (like many others) and I don't have such leaks. the machine specs cannot be the reason, also I would say the Linux cannot. the only difference I see is the TV server, I have only one relay slot. but I cannot imagine either that this should make a difference... anyway you might want to try it...
has the other server a 64 bit version of linux installed? (I know I said it should not make a difference there, but...)

This server and the other server is 32 bit version of linux. The memory seems to creep up and up after every map change. If you change it back to de_dust2 then it still creeps up. The only way to get the memory back is by restarting all cs servers on the dedicated server.
I will update with tests in around 10 minutes.

Can I remind everyone, both servers are configured the same. 11 slot private match servers with 25 slot SourceTV and fps_max 0. Is the above data normal? The way i see it, srcds_linux doesnt release memory it doesnt need especially when people disconnect from the server.
Kind Regards,
Wayne

no this is not normal, as I said. I just tested on my war server. I did several map changes to different maps. The memory usage is always around 280 MB, depending on the map.
but sorry, I don't have a clue what could help you...

Thanks mate, much appreciated.

Well I found the problem to my disappearing memory, SourceTV was on constant record. Someone set tv_autorecord 1, idiot.
