Spontaneous server crashes
Need More Info, NormalPublic

Description

The server sometimes crashes for some reason unknown to me and I can’t understand why. But crashes happen more often when there are more than 10 players on the server.
The most incomprehensible thing is that the number of players can exceed 60 and everything will work stably.
Without players server absolutely stable.

Yep something crashed when receiving a network message.
But I cannot tell why.

Actually.. I do see something fishy. I can get rid of what crashed here. But the root cause will probably crash somewhere else.
If you can somewhat reproduce it (get it regularly), and you have Discord, can you contact me on Arma Discord?
I need to observe this crash happening and get a full dump of it. The automatic crashdumps it creates are only small.

If you have access to the UI/Desktop of your server.
You can run the server with "-debug" parameter. When it then crashes it will show a popup asking if you want a full dump. I need that.

I'm not sure I can reproduce the error since it is extremely spontaneous. I added -debug to the server start parameters, as soon as this happens again I will immediately dump it. Also if i find the stable way to reproduce - I'll write on Discord
