  • Ticket #1361

    • Property Summary Game hangs ~2s into custom-made map → Qbot hangs ~2s into custom-made map

  • Ticket #1361 – Description

    v3 v4  
    1 While developing the wall placement system, I created the attached map to do some basic testing. At some point during approximately the last two weeks (call it roughly between [11494] and [11672]), something changed that caused the game to go into what looks like an infinite JS loop about 2 seconds into the map. This happens only when the window has focus but regardless of the user's activity, and I haven't seen this happen on other maps.

    3 By "hangs", I mean becomes unresponsive and takes up 100% CPU, requiring to be killed from the process monitor. I've observed this happening for revision [11683], the most recent revision at the time of writing.

    55Attaching !WinDbg in a debug build during the hang shows that it's hanging somewhere in !SpiderMonkey as a result of a call to `ScriptInterface::CallFunction_` while doing some AI work.

    4747Attaching to a release build shows similar results: also in !SpiderMonkey, after a result to a script interface call with the `HandleMessage` function name.
