Well, the best I can give is to start ArmA3 join any server and either during the loading screen or right after you load in, this happens 73% of the time. And it crashes randomly sometimes aswell, other than that there is no reproducibility.

It happens on all the missions I have played and on the servers I have played. And yes it does happen on different servers with the same mission and different missions on the same server. With one exception, whenever I play on @BreakingPoint servers.
