Memory Profiler showing huge memory consumption from "Unknown". Any common causes?

[tired smelt]

I did an overnight soak test on a development build and memory usage went from 2.5GB to 7GB.

When checking where the leak is, I get "Unity Subsystems/Unknown" as the only category that increases drastically in size.

Searching this the response always seems to be "Report as a bug to Unity as this is an error in our memory tracking"

However I am in a bit of a rush to solve this, so I was wondering if anyone has any insight into common causes of any Unity subsystem memory leak?

I will be doing some binary tests to try identify the issue, but this does take time so any help would be greatly appreciated!

Unity Version 2022.3.62f1

Maybe related to this

What Unity version are you using?

Updating to the latest minor version could indeed help with engine bugs.

I think this is the latest minor version

I see.

Do you see the increase in memory usage in a non dev build BTW?

It could be some kind of debug or profiling related system for example.

Yes the game crashes after a while on lower memory devices due to an out of memory error even on a non development build

Interesting.
