Hi!
We we are currently facing some crashes in our project.
> # GP# GPU Protection fault. vmid: game process, client: TC5, access: Read
> U Protection fault. vmid: game process,
> client: TC5, access: Read
> ## reason: Unmapped page access, Protection fault addr(VA):
> 0x0000002050a0a000
During the dubbuging process we excluded some cases - firstly saves as it was happening around and media player as we totally changed that to different one. I tried as well enlarging Onion and Garlic memory pools.
I tried to figure that out in Razor dumps and connect it with memory analizer, but addresses that are shown points to empty memory.
We also figured out that running game single threaded doesn’t invoke crash as well as forcing garbage collector to work each frame.
we found out that enabling Gnm Validate on Submit crashes game with same result after loading.
We supose the reason is race condition, but I can’t find what is chasing, and GPU and CPU have access to same memory while it shouldn’t.
Crash doeas not occur on Xbox or PC, Just PS4.
We are using Unreal Engine 4.26 and SDK 8.0, but it happend as well with SDK 7.5 few months back.
Best regards,
Lukasz
