What issue are you seeing?

codex resume fails consistently for one specific session ID. Reconnect retries appear, then it ends with: Timeout waiting for child process to exit. I can see session history, but new prompts never proceed. New sessions work normally, so this seems isolated to the resumed session state.

What steps can reproduce the bug?

1. Run: codex resume sessionID
2. Wait for reconnect attempts (Reconnecting...)
3. Observe failure: Timeout waiting for child process to exit
4. (Tried mitigation) Find and terminate only the stuck resume-related PIDs via pgrep -af codex + kill, then rerun resume
5. Same error persists; only this session ID fails while new sessions are fine

What is the expected behavior?

codex resume <session_id> should reconnect successfully, restore an interactive prompt, and allow sending new messages in that resumed session without timing out.
