Server crush ucrtbase.dll

Description

Hello. I manage the server. We encountered the following problem - after switching (about 3 months ago) to a new PC, the servers began to crash. When the server crashes, a minddump file is NOT created and the RPT file does not end up with the classic error when a server crashes.
Crash occurs only if there are a sufficient number of players, approximately 20+. The more players there are, the greater the likelihood of a crash.

Every time there is a crash, an error is created in the Windows log, where the error module is always indicated as ucrtbase.dll

There have been attempts to update Visual C++, using different versions of it - it does not help. We also rolled back the Windows server from 22 to 19, it also didn’t help. We tried different settings for the number of cores, including disabling multithreading - it didn’t help. We disabled almost all modifications that have scripts - it didn’t help. Full wipe didn't help. We changed the host, processors, and RAM (ddr4/ddr5) several times - it didn’t help. Checking the integrity of Windows files did not help.
We have not identified any indications of specific actions or specific players or locations at which the fall occurs - everything is always different.

To be honest, we are at a dead end, we have tried almost everything possible to solve the problem, but unfortunately we have not found it.
I’ll invite you to the latest log with the crash. As you can see, there is no maindump file in it, but this is a server crash.

@volkovbrs did You manage to fix this?
No crash log, no minidump also

My server also started crashing randomly from 21/06/2024

Reason: Access violation. Illegal read by 0x7ff62f63e893 at 0xffffffffffffffff

"Lacking Permissions, Steam Timeout"

I have seen unauthorised restarts from CF Cloud, for most of the crashes. not sure its happening to a lot of server that i can see on discord channels.

@AlanoItaliano Greetings. We managed to significantly reduce their number, although we are not entirely sure how. My friend also has this problem on his servers. There are no cross mods.
The quantity decreased (in my opinion) when we started using cloud storage of items (special mod), and left a minimum of accessories on the server itself.
However, to this day, the root cause is not clear.

@FUBAR88 @volkovbrs Are you guys running Dayz via TC Admin?

@Cpt.Sauna i am running Omega Manager, TC Admin users are also getting it

i don't know if this is the right post for errors:

Access violation. Illegal write by 0x7ff6ec5695c1 at 0x7ff6ecd695c1

According to some post i have read there is a lot of these popping up many users are experiencing this issue. i have never seen this error also my first time to see it and its daily.

i am running Omega Manager too

Using TC Admin, but also using CF Tools / Gamelabs

Could it be connected to that?

I have logged my own ticket https://feedback.bistudio.com/T182349 for DAYZ PC - Server Crash Reason: Access violation

@AlanoItaliano Can I ask for your contact information to discuss this problem? ideally discord

I would have to wipe my servers and see, because that is when this happens the most. But since last update Ive not noticed any ghost crashes yet. I will update you after my wipe here in a couple of weeks.
