Same problems on Altis Life Servers. Once somebody's game crash by this error, almost the entire server population gets the same crash within the next few seconds.

I've just experienced the situation where not everyone crashed within a few seconds but rather several minutes until pretty much everyone crashed to desktop.
Error report still names BEClient.dll as faulting module.

This is extremly weird. You can't be right, Ezkaton because I already had these PhysX3_x86.dll crashes in the Alpha.

Computing System: 16GB RAM DDR3, Nvidia GeForce 670 GTX, i7-3770K @ 3,5GHz (8 cores), Windows 7, Native Screen Resolution 1920 x 1080, Mainboard ASUS P8B75-M

It does not matter if you are flying a helicopter, driving around with an APC or another vehicle, running across the field as infantry - the hang seems to come randomly. However I have witnessed the game freezing in when running over soldiers with vehicles (for example the Hunter) but I cannot say exactly if that's the trigger which causes this problem. After 290hours of playing ArmA3 this is what I have noticed.
