Hi, Thanks for your answer. I had already tried adding <dynamicallyIncludedDestination> and now tried the <staticallyIncludedDestination> but neither of them help.
I just noticed that when this problem occurs the "MessageCountAwaitingAcknowledge" of the queue subscription for the Server.in queue named NC_Server_inbound_Client in the client gets high and stays there. I assume that this subscription belongs to the Network Connector and is the one forwarding the messages to the Server. So it seems that the Server broker is not acknowledging those messages. I tried modifying our code to see whether the problem is in the message acknowledgement there. We were using auto acknowledge before, but I also tried with client acknowledge. However this did not change the situation in any way.
