wsl2: usage of %LOCALAPPDATA%\Temp\wsl-crashes #12147

Host OS: Windows 11 23H2 22631.4169
Guest distribution: ubuntu, kernel 5.15.153.1-microsoft-swandard-WSL2

Something in my WSL environment is causing failed nodejs commands to write crash dumps to %LOCALAPPDATA%\Temp\wsl-crashes in the host fs. This is annoying because I have a lot of RAM and the crash dumps are big, and Windows gives me notifications that my disk space is running low.

I've searched for information about this, but the documentation about crash dumps refers to WSL2 subsystem crashes, and these are crash dumps from command line programs running in the guest OS.

I would like to be able to disable this behavior or relocate the directory where the crash dumps live. Is this possible? Could it be possible? Is there documentation that I am missing?

#12032 is definitely the cause of the files that I'm seeing, but the thing I would like is the ability to change where they are written or disable them being written to the host FS.

@sfoster1: You can disable crash dump collection by setting:

[wsl2]
MaxCrashDumpCount=-1

In %USERPROFILE%/.wslconfig. After WSL restarts, this will completely disable crash dump collection.
