Moving the MontanaWorld.ent into a subfolder like \World also does not work:

Hi Geez,

Same problem here. Happened first time yesterday (11th of May).

Dont know - maybe - unfortunately we dont have tools to debug navmesh.

Unfortunately does not help. Not using smin/smax -> Problem still exists. No Zs.

Unfortunately, I can't say anything specific about this, as I only run a local test server without players to test my map. At first we thought that the problem only occurred on my Deerisle map. At first I had deactivated all my own scripts in order to exclude the possibility that the FPS drops were triggered by them. Unfortunately, this did not lead to success, so I started to work on the animal system. There were first signs that the problem might be hidden here. The team was kind enough to test other maps. Namalsk & Chernarus. Even though it was a bit more difficult to reproduce the problem here, it was ultimately possible. What complicates the diagnosis here is the fact that there is no debug possibility for us to get insight into which "systems" in the DayZ server need a lot of FPS performance, and that the error seems to occur so irregularly. However, the error pattern is usually the same: The server suddenly loses (without players) FPS performance up to 80-90% for usually about 15 minutes - sometimes a little longer. I don't know if it would be possible to get additional debug options in future DayZServer versions, which would tell us which systems (AI, Navmesh, Physics,...) currently need a lot of resources.

Can confirm this FPS Drop Problem:
