maybe an update for you guys since the issue is still open.
im on windows server 2012 and had this issue for a while during december and my server was crashing like once a hour or something. When trying lots of thing to fix it i change 2 major things and it stop crashing, its been 48 hour now and still up. (Auto reboot each 6h)
What i change:
old version of extDB -> extDB2 release 70
change all my BIS_fnc_MP (and life_fnc_MP because i have an Altis Life server) to remoteExec and remoteExecCall
i dont really know if it fix the crash but at least it give me enought time so the server can reboot by itself every 6 hour
