I've had this problem for just over a week now, and no matter what I do, I cannot get the server to stop freezing unnecessarily on startup.
The server is an Altis Life Server. Pre-1.58 release it's startup time was 20-60 seconds... now it has a startup time of at least 16 minutes.
I've upgraded the server's hardware, commented out certain tasks and added in diagnostic lines... nothing is allowing this server to start up correctly anymore.
At the time of the 1.60 release we also included the 3DEN map we created from scratch due to the 2D editor being removed... this seems to be the cause as to why the server freezes at startup. When we preview the map in 3DEN, either 3DEN crashes arma out, or the character is frozen for the first few minutes.
1.58 only extended the startup time to around 3 minutes, but with the 3DEN map and 1.60, the server is becoming unusable. I've already paid over £250 looking into this issue, so please can someone from BI look into this now.
