> On the k8s+docker environment, the 1 jobmanager container and 5 taskmanager
> container are the standalone cluster modes.
> {color:#FF0000}But for some reason, the jobmanager is rebooted, and two of
> the remaining three taskmanger are also rebooted, and two of the remaining
> three taskmanger don't connect to jobmanager, resulting in insufficient slot
> resources reporting errors.{color}
> The attachments are the jobmanager log, two disconnected taskmanger logs, and
> all available and unavailable taskmanager screenshots of flink at the time.
> It is strange that two rebooted taskmanger can connect with jobmanager, and
> one of the three unrebooted taskamanagers can connect.
> Why?Can the cause of the restart be analyzed from the log?thank you
