Heartbeat timer stops after first batch - scheduleNext() timer never re-fires
증상
The heartbeat runner’s internal timer fires once after the configured interval, runs all due agents sequentially, but then never re-arms. After the first batch completes, no further heartbeat runs are triggered until the gateway process is restarted.
원인
OpenClaw gateway, skill, or agent configuration issue — root cause confirmed in the openclaw/openclaw issue tracker.
해결법
External watchdog script that runs openclaw system event --text "watchdog-heartbeat" --mode now every 10 minutes from within the container. This bypasses the internal timer entirely and reliably triggers heartbeat runs.
