    Hi @ All,

    yesterday i wanna play a round of counterstrike:source an run in massive troubles :frown: When i start to get the serverlist i recognized that scanning the servers gets very slow. So later on i checked the syslog and see that there was an error message: "ip_conntrack: table full, dropping packet" than i set the value from 2048 to 4096. After getting back to counterstrike i tried to load the serverlist again but after a while i lost internet connectivity. I recheck the syslog and see that the router had rebooted. So after long observations i recognized that every time i load a new serverlist the conntrack connection raises over 4000 connections and the router run out of memory and than cause a reboot. Whats going on here. I dont know if this is the fault of new version 1.06 because i never had this problem before. Later on i will try to flash back and will see if the problem is still there. Anyone an idea ?

    btw: there is no problem with p2p ! It seems to be only with steam.

    I use it all the time no with no problems... I think your problem lies elsewhere.
    my connection limit is set to 2048 since I don't really use more than that and
    I got 4 computers connected to the router all running bittorrent and emule.

    i use Qtracker, a Game-Server-Lister, and had nearly the same problem, except the rebooting, it only disconnects the wan-Con.
    Only work around is setting Maximum Connections to ~6000, and lowering the connections used for quering the servers in Qtracker. (I've seen it opening 5000 and more)

    Same over here with other programs. I have to set the connection limit much higher in order to receive a stable connection.

    The problem is most serverlist software (ingame or 3rd party) is it has to connect to all the servers in a very short space of time to probe them for information. To get that information from so many servers, it will have to open a connection to each and every one of the servers. If your serverlist have a thousand servers then it's gonna request/open a thousand connections. Reason why your p2p programs aren't affected is most of them only default to around 100-200 max connections.

    Try increasing the max allowed connections to 4096. Personally I use 8192 without problems, although my max connections have never really reached past 3000. Another tip is to set your serverlist software to only list/refresh servers close to you, as many will allow you to filter by country etc. Not much point in probing servers half way across the globe with pings over 500+ ms, it's not like your gonna play on them are you?

    found a solution for the steam problem in their own forum :)
    The problem with crashing the router was of setting the value of conntrack table to high! (>6000) -> router run out of memory. So now i'm back at 2048 (as in the beginning :biggrin: ) and if there is an application (like steam ((without reghack) witch start a lot of sim. connections) dont worry about if there is an "[SIZE=-1]ip_conntrack: table full, dropping packet" in the syslog. For me it doesn't affect performance (after a while of testing:wink:).

    it was a discussion about the connection limit and GeeTek seems to be buried in his position there is no correlation in the actual problem.
    I think only in symptoms eventually since memory will run out...
