Endless "Net sim post start" after update to 2.9.18.12722

[Shot]

Since I updated to 2.9.18.12722, I can't connect to any server anymore. The game is stuck, DCS is using ~20 GB memory and 15 GB GPU memory but does never complete the loading process.  My buddy saw that I'm connecting on the server... but that's it, I'm seeing the loading screen with that message.  Any ideas?  I've repaired the installation, removed all mods, restarted my router, rebooted my PC and cleared the fx and metashader files...

Well after giving up for some time, I can now report that the issue still kind of exists although it got better again. The symptom however still remains: On some servers (e.g. "[PL] Gildia.org - Dynamic Range Germany (Cold War) PvE", my machine is stuck at "Net sim post start" for around 3 minutes. I can join any other servers (also with the Germany CW map) but none takes that long. The issue just appeared since the last patch, before I never even had observed that message during the loading process. My machine is a i7-10700K with 64 GB Memory and a 5090.

hello. are you able to ask any other participants of the server with the problems? logically, it seems like a server problem. perhaps there a lot of backend scripts loading you are not aware of. you can also post DCS.LOG from a session that takes a long time.

please attach your dcs log. It should have more clues 

Thank you

I'll do another clean connect the next days and will provide the DCS.log.  At one occasion, I had waited 10 minutes before I killed the app.  My buddy who was already on the server has seen my connect but I obviously never made it.  Waiting 3 minutes might be annoying, waiting 10 minutes is impossible  I'll provide the log...

Did two tests just now with all Mods removed (I hope) and a clean logs folder. I've measured from the moment I clicked on the join server button:

1) Server "[PL] Gildia.org - Dynamic Range Germany (Cold War) PvE": DCS loads 2:40 minutes until "New sim post start" appears.  This time it took ~2.5 minutes this time before it proceeded and i can select a coalition. Logs are attached as 1st_run.zip

2) Server "105th SSF | [GER] COMMUNITY SERVER": Same Germany CW map. After 45 seconds, the "New sim post start" appears. After a total of 1 minute, that's done and i can select a coalition. Logs are attached as 2nd_run.zip.

 

Why does this sometimes take 2-3 minutes and sometimes (I assume) a normal few seconds only?

The only thing I found in the logs which takes ~2.5 minutes is that one here:

2025-08-05 20:09:02.443 INFO    WEATHER (Main): reset fog animation
2025-08-05 20:11:19.742 ERROR   ED_SOUND (18140): can't load wave: "effects/weapons/automatic/warrior_distant_1.wav"
 

That a mission thing? Thanks for any help!
