      Description

      The startStatusUpdater thread waits for the isStopped variable to be set to true, but it is waiting for the next heartbeat. During a reboot, the next heartbeat will not come and so the thread waits for a timeout. Instead, we should notify the thread to continue so that it can check the isStopped variable and exit without having to wait for a timeout.
