A question for the "Stopping watcher service" message

Does anyone know what could cause the following message in the log?

stopping watch service, reason [watcher manually marked to shutdown by cluster state update]

The service looks like stopped but not sure what could cause this.

Thanks in advance

Hi @chulkim. Was anything happening on your cluster at the time? For example that can happen during an upgrade. Watcher is restarted automatically after the upgrade. Is watcher currently running?

Also, do you see this once in the logs? Or do you see it repeatedly?
