Sub-agent embedded run timeout does not release CommandLane, causing all subsequent webchat messages to be queued indefinitely
증상
When a spawned sub-agent (embedded run) times out, the parent agent’s CommandLane lock is not released. This causes all subsequent messages sent to the parent session (via webchat) to be queued indefinitely — the webchat shows a permanent loading spinner and never receives a response.
원인
OpenClaw gateway, skill, or agent configuration issue — root cause confirmed in the openclaw/openclaw issue tracker.
해결법
Restart the gateway service:
systemctl --user restart openclaw-gateway
This clears the stuck lane state and allows messages to be processed again.
