> Most communication channels used by monitor processes to exchange cluster state information and to handle failure detection must be changed to asynchronous IO with timeouts and retries to allow for the removal of a monitor process from the cluster communication. This is to prevent a  'Sync Thread Timeout' failure of the entire cluster instance where a monitor process or it host server becomes unresponsive due to a server or network failure.
