Description

Hello,

I'm reaching out to ask for your help or a fix. I've been trying to debug this issue since version 1.28. Everything was working fine before the update. Now, while the server can still start, it only works with far fewer of our mods (which we paid a lot of money for).

Here's the issue: it seems that since version 1.28, the server no longer starts, possibly due to the number of mods. Every time we try to launch it, we get the following DayZ error:
Access Violation – Illegal write by 0x7ffdb57612de at 0x26529b5b000.

We’ve been trying to solve this since the update, without success. Here’s what we’ve tested so far:

Booting with fewer mods → the server starts.

Booting by swapping some mods out and putting others back in → the server starts.

We’ve repeated this several times, and the server always starts under those conditions.

However, when we try to enable all the mods again → the server refuses to start.

So we started trying to isolate each mod, one by one.
This led to hundreds of restarts to find which specific mod might be causing the problem… but the strange thing is: none of them are.

Let me explain: if we remove mods one by one, at some point the server will successfully start. But if we then add back the last mod we removed (the one that supposedly made it work) and re-enable everything else, the server fails again — even though this mod worked fine when others were disabled. We've repeated this process over 80 times, and we are now fairly certain that the issue does not come from any single mod.

This leads me to believe there might be some kind of mod memory usage limit or hard cap introduced in 1.28.

I’ve searched everywhere but haven’t found a solution. We’re asking for your help, as our server has been completely blocked for quite some time now, and we’d really like to get it back online for our community.

Thank you in advance for your support.
