Repro Steps

Don't have reliable repro steps, but every once in a while my WSL will just freeze and the VmmmemWSL process will not use up much CPU but will peg the disk and use tons of RAM.

Usually happens when I run gradle.

Sometimes, in this state, even wsl shutdown doesn't work:

> wsl shutdown

A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.
Error code: Wsl/Service/0x8007274c

Usually need to reboot Windows to get things working again. Logs attached.

Happens once in a while (~1/wk)

Expected Behavior

No freezing

Actual Behavior

freezes

@marchello2000: by "wsl shutdown", do you mean "wsl --shutdown" ?

Regarding the hang, looking at the logs, I see a lot of plan9 traffic but that's one enough to root cause.

Next time this happens, can you share a /dump of the WSL processes ?

[microsoft-github-policy-service]

Hello! Could you please provide logs and process dumps to help us better diagnose your issue?

To collect WSL logs and dumps, 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 -Dump

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!

Also, another thing: I see that you have swap disabled. That can potentially cause a hang if WSL runs out of memory. Can you try enabling swap again in .wslconfig ?

Same for me. My workaround is to kill the process in (admin) PowerShell and then restart WSL:

taskkill /f /im wslservice.exe

[vmnit]

Same here. Facing keyboard input freeze after every one command.
Even facing issue with the same frequent freeze while writing in the nvim.

wsl shutdown seems to be overkill. It seems that some service is getting high priority over the keyboard input, and that is causing these frequent freezes.
Not sure, if there is a setting which can help here.

If anyone has any solution, please share.
