Segmentation fault crash on map change

If someone plays on my server and a map change occurs the server crashes with a segmentation fault. However, if no one uses the server, I can change the map without it crashing.

I'm confused about why this is happening.

I'd appreciate any assistance with this. Thanks!

    When i check you're log, the segementation error occurs when no one is on you're Server too

    Maybe disable web Server or check what causing this error.

    Have you already updated you're Server to Build 271?

    Here is the Mailing List, so you don't miss any updates

    SteamOS? Is it supposed to work on it? I guess there's nothing technical speaking against it.
    If the webadmin webserver doesn't start anyways, just disable it by not defining it in the start params. (Just as wooz said)
    Have you tried it without any mods?

    Ok let me clear this up a bit:

    This issue is kinda known and was tracked down to some jit ffi callback issue and is happening at both OSs (slightly more often at Linux thought). And we are kind of trying to figure out atm what is going wrong.

    If you want to help us debugging, please attach gdb to the ns2server process and run gdb bt after a crash:

    More details here:

    https://wiki.ubuntu.com/Backtrace (Afaik SteamOS is a branch of debian and as ubuntu is also a branch of debian yeah that tut also applies on SteamOS)

    Post the backtraces afterwards here in the forum or mail them to ns2cdt[at]gmail.com ;)

    A similar problem. Server crashes at varying intervals at start voting map.

    I haven't got any news beside that this issue is related to some kind of a core issue of the luajit vm. To this day we still haven't found any steps to reproduce this crash (and i invested quiet some time into it).

    Furthermore related issues are showing up at mostly all kind of places. Lately we found even a critical client issue possible related to this one. But as we don't have any hint about the source yet i can't tell you anything in detail about it.

    So far we are still investigating. So no idea when this will get fixed.

    For now i recommend you as all ns2 server operators to use monitor scripts to auto-restart your server in case it freezes or crashes as we have these kind of issues around since ns2 got released and i guess we will have them around for quiet some time even if we are able to fix this one.

    For Linux there is even a good server script collection available: http://danielgibbs.co.uk/lgsm/ns2server/

    @artem this thread already covers that crash. Happens during pregame only, on initialisation of one of the vanilla votes. Could have something to do with players still loading while the vote gets initiated. Got no solid reproduction steps, just plenty of crashdumps.
