Same event is received multiple times

I am using this code to receive NewEventIndication:

MessageCommunicationManager.Start(EnvironmentManager.Instance.MasterSite.ServerId);
 
_messageCommunication = MessageCommunicationManager.Get(EnvironmentManager.Instance.MasterSite.ServerId);
 
_eventHandler = _messageCommunication.RegisterCommunicationFilter(OnNewEventIndication, new CommunicationIdFilter(MessageId.Server.NewEventIndication), endpoint, EndPointType.Server);

Everything works fine, but when I register another message communication to NewEventIndication (using the code above), each MessageReceiver starts receiving same event twice. If I register a third message communication, I start getting same event three times.

Is it possible to make each MessageReceiver get event only once?

Hi. Thank you for your detailed report! We have investigated this and found that it really happens if you do it within the same application. We will have a look into this issue. If you need several receivers in the same application to subscribe to the same event, then for now you can use a workaround by registering to the event once and then internally send your own notification to all your receivers.
