System.OutOfMemoryException

[M00nBack]

Description

If too many assemblies are opened, a System.OutOfMemoryException error will be reported when searching, but in fact I still have a lot of free memory that is not used.

@M00nBack are you running 32-bit dnSpy instead of 64-bit? 32-bit processes on Windows are still capped at 2GB RAM*

Try using 64-bit dnSpy, you should only need the 32-bit binary for debugging 32-bit processes.

*can be 3GB-4GB depending on different conditions, see https://learn.microsoft.com/en-us/windows/win32/memory/memory-limits-for-windows-releases

As mentioned, please use the 64-bit version of dnSpy. This allows dnSpy to use all of your available memory. Due to 32-bit addressing limitations, 32-bit dnSpy can only utilize 4GB of RAM.

If this issue still occurs when using the 64-bit version, please provide more exact steps to reproduce the problem. If you are analyzing a specific file(s), upload it here or send it to me at elektrokilldev@protonmail.com.
