    It has killed my servers two times already AFTER the latest update.

    Why does it have to crashes anyways?
    Can't it just cancel the "stuck" API call if that even happens? Or the current API code doesn't allow it?

    Current API client code is a big big mess, mostly cause it's written by a python programmer who'd clearly taken some course in C years ago and applied that to C++. By the time we realised it was like that it was already "functional" and therefore unlikely to be replaced; as they say - "broken code gets fixed, bad code stays forever".
    The three people we've had "going to fix it" haven't. I don't want to because I want to move away from this engine, not invest more and more time into fixing bad code I didn't write. It's technically on the TODO list but it's under the heading "shame hole".

    Sorry for being frank about this.

    E: slightly more info - the current API client has no idea of "cancelling" actions, though it does essentially have "in flight" actions - the problem is (as the error messages suggest) that if one of them locks up for whatever reason (bad code, remember), it just sits in the "in flight" list forever, and whatever was waiting on it (99% of the time just a server status update) never gets completed. The "fix" (as it says, nuking the list) is so that it'll at least attempt more actions and not leak too much memory, but in general requires a full rewrite of the API client to get a clean solution. The actions as they are are relatively unsafe, global variable bound functions in threads; as you might imagine, them being unsafely ended (or ones after them starting and working on the same data) is what leads to the list filling repeatedly, and eventually crashes.

    Not currently. Having a better connection on your end can help avoid the threads dropping but nothing's "100% fail safe". Most people run the server via a script that re-launches the game after it crashes. Joe (afair) also has a script that resets them if they're eating too much cpu/ram after posting a message to the game that the server will restart, but it's been a bit hit and miss functionality wise from what I've seen.

    For some reason it's on linux only? everyone i know had this problem on Linux. my friend @Chrispin hosted a Windows server with the same settings and it never crashed for him.

    its weird, I was hosting the gather sever and it kept happening everyday. somehow it just stopped happening and I was never able to retrieve the full back-trace by running it through a debugger.

    It's random. A lag spike and there you go. A good host helps a lot.
