What to do when WSL2 decides to eat all your RAM. - Thu, Sep 29, 2022
What to do when Windows Linux Subsystem 2 decides to eat all your RAM.
I left several WSL terminals running over night and when I returns I noticed my PC (that is a personal computer) was running slow. I checked the memory usuage and a process named vmmem was using nearly 32g. After a bit of research aka typing my problem into Google and clicking on the first LINK, I found out that vmmem is the process that handles the system resources of the virtual machine WSL2 runs in.
wsl --shutdown to free up the memory. Then created the file
%UserProfile%/.wslconfig1. This will limit the RAM used in the future.
