Good day. We need a helping hand to find out what is causing server to crash.
Windows 10 Dedicated x64 server + HC

02-44-51 crash says out of memory
13-41-49 is... not sure. Something certainly went wrong there but I cannot see how. If you have more reports of the same crash they might have more info.
Also I'd recommend to run profiling/performance branch, they have lots of bug fixes and are also easier to analyze crashes for me

Thank you for taking your time to investigate.

  • Here's everything we have at the moment (doesn't mean there were just this much crashes - previous dumps just got deleted), hope it could be useful

  • We'll install prof/perf branch and gather more data, thank you

We switched to profiling branch and it wasn't crashing for a couple of days, but today it did again

More crashes recently

These are good captures
Sadly the first 4 are still stable branch, looks like its all the same as the last one I checked. But cannot really see whats going on.
And the new ones.. ugh.. you renamed arma3serverprofiling_x64.exe to arma3server_x64.exe, That just turned this from easy to really annoying

Ok I got it.. I can see where its crashing, but not why.
It doesn't make sense.

Its related to some Car...
I cannot see more in the minidumps.
Can you get me a full dump, by loading this mod on the server
But the full dump will be very large, you can 7z pack it but you probably won't be able to upload on here

It finally crashed again, unfortunately mod did not load

20:50:07 "ArmaFullDump initializing"
20:50:07 CallExtension loaded: ArmaFullDump (C:\NWG_PL\Arma3Server\@ArmaFullDump\ArmaFullDump_x64.dll) [Arma full mdmp]

20:50:07 ["ArmaFullDump Init:","fail$"]

One more thing: One of the players claim that server crashed the moment after he attacked friendly UGV Saif located on the base with artillery fire and says that it happened at least once before. I kinda (kinda) can confirm that - when I tested new attack planes behavior sometimes plane would target that Saif (along with other vehicles) and my Editor would crash, this happened several times before I switched to testing in an empty mission. I'm not sure but this might be worth the check.

UPD: My colleague also confirms crashes happening on Saif elimination.

Uff yeah. Well thats just the same crash again. I guess I need to fix ArmaFullDump again, but I thought I just fixed it recently :/
I don't know when I will have time to do that, maybe end next week
