I've uploaded wsl logs.
benhillis commentedon Aug 3, 2022
Thanks for the logs. The issue here is that sshd is not tied to a wsl.exe or wslhost.exe on the windows side (which handles interop requests). I have some thoughts on how to fix this, let me think about it a bit.

looks like i have the same issue

I'm facing this issue with Docker Desktop running from under WSL
But not always, randomly.

we need to solve this problem, it's too annoying

I'm also randomly getting similar issues.
In my case, I get an error(
UtilAcceptVsock:248: accept4 failed 110) when I login to Ubuntu.I am using fish-shell as our Ubuntu login shell.
config.fishcontains the following:set -x WINDOWS_HOME_DIRECTORY (wslpath (wslvar USERPROFILE))log is here:

yeah man you get it. the problem about my wsl has been fix through this method
bigfree commentedon Apr 12, 2023
I have no idea how this setting can solve the problem, because the value
enabledoesn't exist in the official documentation.There is a value
enabledand its default true.MitchellBot commentedon Jun 6, 2023
I get this on occasion and removing
"credsStore": "desktop.exe"from ~/.docker/config.json fixes it.sherif-elmetainy commentedon Jun 18, 2023
I had the same problem and James Mitchell (@MitchellBot)'s solution fixed it for me. Thanks a lot.
patricknelson commentedon Nov 15, 2023
Bizarrely, I got this error too when running an
exefrom WSL2 (in my case,git-credential-wincred.exe) and the "solves all" quick fix of restarting WSL apparently worked for me as well. i.e. from a command prompt:Also worth a shot for anyone else. Interestingly, this was only an issue for me after applying a Docker Desktop upgrade as well. Very odd.
Rcardu commentedon Nov 22, 2023
my hero!
Moscode commentedon Jul 3, 2024
This worked for the similar issue that I had. The ERROR code was UtilAcceptVsock:250 instead of UtilAcceptVsock:246.
ColumbusAI commentedon Sep 13, 2024
Still getting this error when trying to run a llamafile in WSL2. Ben Hillis (@benhillis) quick mention to see if this is on the team's radar?
kodie commentedon Sep 19, 2024
Adam Mikó (@bigfree) is correct. Adding this to your config will cause a
wsl: Unknown key 'interop.enable'error.This is what worked for me.
ColumbusAI commentedon Sep 19, 2024
To clarify, the error I receive is this:
<3>WSL (5984) ERROR: UtilAcceptVsock:248: accept4 failed 110
It is not resolved by enabling or disabling Interop as I have tried both methods.
fchastanet commentedon Oct 21, 2024
I had the same issue and I remarked that most of WSL RAM was used
I stopped one vscode that was taking more than 4GB of memory !
I re-run vscode and this error disappeared
nouritsu commentedon Feb 21, 2025
From microsoft/wslg#1308
I am running NixOS 24.05 and this issue happens to me when trying to use win32yank.exe from WSL.

I sometimes get this error when running docker builds. Docker is using the WSL 2 based engine:
A restart of my computer sorts it, but's very annoying.

This is the best incantation I know to restart WSL as background job without leaving an Administrator PowerShell console open:
wsl --shutdown; Start-Process wslThen close the PowerShell console.

I also had same issue while opening the VSCode through WSL window.
Thanks.
