All WSL commands hang (including wsl --shutdown) but WSL is constantly using 30-40% CPU

Repro Steps

This mostly seems to be happening when the device wakes from sleep - after a system restart, I can access the WSL distro as expected

• Start a WSL distro (Ubuntu 20.04)
• See it hang
• Try to do a wsl --shutdown
• See that hang as well

Expected Behavior

• Start a WSL distro (Ubuntu 20.04)
• The command line should open

Actual Behavior

• Start a WSL distro (Ubuntu 20.04)
• The terminal hangs completely (see screenshot above)

I have this issue as well. Killing the WSL process from taskmanager recovers, but it does it again. Especially (but not only) after it comes back from sleep.

Looks like something is wrong with your trace, could you please collect a trace using these instructions?
/logs

Hello! Could you please provide more logs to help us better diagnose your issue?

To collect WSL logs, download and execute collect-wsl-logs.ps1 in an administrative powershell prompt:

Invoke-WebRequest -UseBasicParsing "https://raw.githubusercontent.com/microsoft/WSL/master/diagnostics/collect-wsl-logs.ps1" -OutFile collect-wsl-logs.ps1
Set-ExecutionPolicy Bypass -Scope Process -Force
.\collect-wsl-logs.ps1

The scipt will output the path of the log file once done.

Once completed please upload the output files to this Github issue.

Thank you!

Could you also share the output of wsl.exe dmesg?

Thanks!

I'm not the original poster, but I'm having a similar issue: every wsl command hangs (including wsl --shutdown), this causes problems with Docker, but because of the issues with WSL I can't even reinstall Docker itself (I initially thought it was a Docker issue but everything seems to point back to WSL).

wsl.exe dmesg also hangs so I can't post its output.

I attached the logs from collect-wsl-logs.ps1:

Same problem here. Killing WSL from Task Manager solves the issue but is obviously not ideal.

Same here; this just started happening in the last few days; Please re-open this MSFT!

[georcon]

Same here. Need to terminate the process from task manager. This issue started after updated WSL to the Store version.

This should not have been closed - maybe the person went on vacation (7days?)
Happens often when attempting to switch folders using VSCode. Hangs -- generally just reboot to get back to working again for a while.

Please reopen, this issue should not have been closed. This happens all the time, usually after waking the computer from sleep. Usually a simple wsl --shutdown worked after a ~30s wait, but today even this method failed as all wsl commands hang indefinitely. I need to go into task manager and shut down vmwp.exe, as otherwise the vmmem process persists even if I kill all wsl processes manually, and the wsl commands hang anyways.

This problem is really frustrating as it forces me to restart Docker and all containers, as well as my IDE, which with large projects can take some time.
