Background of the matter

When I started my computer as usual, the following error was displayed.

Details are as follows.

WSL distro stopped while waiting for Lifecycle server.

(Maybe this is) cause

It seems that there is not enough memory for Docker to run WSL2 at startup, causing an error.

solution

I used .wslconfig to limit memory because Vmmem messed up memory. Due to this limitation, it is possible that you ran out of memory when you started Docker. So, I will rewrite it referring to this article.

Before rewriting

.wslconfig

[wsl2]
memory=6GB
swap=0

After rewriting

.wslconfig

[wsl2]
memory=10GB
swap=0

I fixed it from memory = 6GB to memory = 10GB and rebooted and it worked. There is no particular reason to set it to 10GB, so if this method doesn't work, try another method or change the amount of memory to increase.

Or, although I haven't tried it, it may be possible to solve it by setting swap = 1. Please refer to this article for the meaning of swap = 1.

finally

Thank you for reading this far. If there are any mistakes in the article, please let us know in the comments.
