Network crashes - Connectivity to ubuntu guest fails after file upload / network stress

[joachimnielandt]

Version

Microsoft Windows [Version 10.0.22000.778]

WSL Version

• WSL 2
• WSL 1

Kernel Version

5.10.102.1

Distro Version

Ubuntu-22.04

Other Software

Client: Docker Engine - Community
Version: 20.10.17

Repro Steps

Network connectivity seems to drop after stressing the network. I experienced this by

• running a tomcat docker container and uploading a large (200MB) .war file - invariably this fails
• running iperf3 server in ubuntu and iperf3 client in windows - after a while this fails

After failure, I cannot ping my docker services or connect to my iperf3 server. After wsl --shutdown, network is restored (until it fails again). Services remain running in WSL though: I can access them from within Ubuntu, just not from Windows.

Expected Behavior

Network connectivity remains, even when stressed.

Actual Behavior

Network fails.

Diagnostic Logs

Not sure how to proceed - is it possible to generate a network-stack debug log for WSL?

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.

Pleasure, thanks for pointing out how to create a log file, wasn't aware of this option before. I have added the log output as requested.

I created a second one, this time a bit more concise I hope. I did the following:

• shutdown wsl
• started docker inside
• initiated the tomcat upload of the .war file
• saw the network crash occur
• initiated a wsl shutdown.

This might be relevant, but not clear to me at this point. There's plan9 and docker activity (involving port 8080, which is exposing tomcat). Couple seconds later, the host network service is stopped?
