> Since ExpiringMap.shutdown() shuts down the static executor service, it cannot be restarted
(and in fact reset() makes no attempt to do so). As such callbacks that receive no response
are never removed from the map, and eventually either than server will run out of memory or
will loop around the integer space and start reusing messageids that have not been expired,
causing assertions to be thrown and messages to fail to be sent. It appears that this situation
only arises on bootstrap or node replacement, as MessagingService is shutdown before being
attached to the listen address.
