Yeah ;) always a pleasure with BattleEye, Punkbuster and all the other nice tools :P

I just tried a few things:
#1 playing a normal mission with my standard mod set (CBA + VCOM) and BE enabled
-> server load is pretty normal, ~50-80% load on one of the 4 cores and ~2 gb / 12 gb RAM used
#2 playing with @alive but without @aliveserver and BE active
-> I cannot connect, same problem as before, I simply cannot get past the loading screen
#3 checking the open file limit
it's pretty large on my root server ~1,2 million should be more than enough

Usually we play with a few friends, so disabling BE should be no problem to get started with alive.
But if you get more info or someone in the discord channel comes up with any solution please let me know :)

Thank you for your help.
