> private Map<String, Long> hostResponseIds = new HashMap<String, Long>();
>   private Map<String, HeartBeatResponse> hostResponses = new HashMap<String, HeartBeatResponse>();
> {code}
> Noticed spurious re-registrations because the responseId from agent was not recognized by the server. It seems to be due to lack of synchronization around the above fields considering multiple threads may modify the map.
