Codex Desktop regression after 26.803.61601 update: WebSocket Broken pipe leaves task stuck #37894

Description

Immediately after Codex Desktop updated at approximately 6:38 PM ET on August 10, 2026, an existing task became stuck after a WebSocket disconnect.

The user-visible error was:

stream disconnected before completion: failed to send websocket request: IO error: Broken pipe (os error 32)
stream disconnected before completion

Environment

• Codex Desktop / ChatGPT app: 26.803.61601 (build 6396)
• Standalone Codex CLI installed locally: 0.147.0
• macOS
• Local project task
• Large, image-heavy session history: approximately 255 MB

Observed behavior

1. The app updated at approximately 6:38 PM ET.
2. A turn in an existing task then disconnected with the Broken pipe (os error 32) error above.
3. Retrying in the same task was accepted but produced no assistant, reasoning, tool, completion, or visible error event.
4. One retry remained empty for about three minutes before interruption.
5. A subsequent retry remained active with no output, leaving the task stuck.
6. Restarting/retrying in the same task did not recover it.

Expected behavior

After a transient WebSocket disconnect, the turn should either reconnect and complete, or terminate with a visible recoverable error so the task can be retried normally.
