We are using TCP to set up Eventlistening between two load balanced servers (UDP is not possible in that enviroment) and usually it works fine but when we are deploying updates if we not shut down the site first, or when there are a recycle of the application pool we gets a error on the startup that says like this:

Error creating/opening service host for event replication class

System.ServiceModel.AddressAlreadyInUseException: There is already a listener on IP endpoint 0.0.0.0:14000. This could happen if there is another application already listening on this endpoint or if you have multiple service endpoints in your service host with the same IP endpoint but with incompatible binding configurations. ---> System.Net.Sockets.SocketException: Only one usage of each socket address (protocol/network address/port) is normally permitted

It goes away after a minute or so but for that minute the site is gone, not working.

We never saw this when we were able to use UDP.

Anyone knows how to do to make this go away?
