It’s one reason i don’t like WSL2. When you compile something which needs 30 GB RAM the only thing you can do is terminate the wsl2 vm to get that ram back.


Since late 2023, WSL2 has supported "autoMemoryReclaim", nominally still experimental, but works fine for me.

add:

[experimental] autoMemoryReclaim=gradual

to your .wslconfig
