What issue are you seeing?

Date: 2026-06-25
User environment: Windows host + Ubuntu 24.04 WSL2
Codex CLI version: 0.142.2
Codex install: standalone Linux x86_64 under /home/pouma/.codex/packages/standalone/releases/0.142.2-x86_64-unknown-linux-musl

Summary

Codex CLI usage appears to correlate with recurring WSL instability on this machine. The practical symptom is that WSL becomes unreliable enough that the user has to run wsl --shutdown from Windows to recover the session.

This is not just a slow command or normal network failure. During the current failure state, WSL-to-Windows interop commands fail immediately:

$ wsl.exe --version
<3>WSL (3 - ) ERROR: UtilBindVsockAnyPort:309: socket failed 1

$ powershell.exe -NoProfile -Command "[System.Environment]::OSVersion.VersionString"
<3>WSL (3 - ) ERROR: UtilBindVsockAnyPort:309: socket failed 1

This suggests a WSL interop/vsock failure after or during Codex CLI activity.

What steps can reproduce the bug?

Uploaded thread: 019efeb1-328c-7df2-9189-1c0f2df2cc56

What is the expected behavior?

No crash when i want to use codex cli in wsl
It's unusable. I took a paid subscription and i can't use it properly. I'll return on Claude code if it persists

Additional information

No response

[Nicolas0315]

A useful next split here is whether ordinary Linux-side commands still work at the failure point and only WSL-to-Windows interop/vsock calls fail. If this reproduces again before wsl --shutdown, a minimal sanitized capture like this would help separate Codex child-process/resource pressure from a host WSL interop failure:

date -Is
cat /proc/sys/fs/file-nr
ps -eo pid,ppid,stat,comm,args | grep -E 'codex|node|bash|sh' | grep -v grep
timeout 5s codex --version
timeout 5s wsl.exe --version
timeout 5s powershell.exe -NoProfile -Command '[System.Environment]::OSVersion.VersionString'

Please avoid pasting environment variables, auth files, full shell history, or unredacted logs. The key distinction is whether Codex/Linux process activity is also wedged, or whether Linux remains healthy while Windows interop calls immediately fail with UtilBindVsockAnyPort.
