I am having connection issue to the Open DACS daemon server. My test is based on the Content Based Subscriber tutorial. After 1-2 successful connections, I will start getting AuthorizationConnection.CONNECTION_DOWN which rejects my connection and it will work again after a few minutes. For all the successful connections, I am properly closing the connection after the entitlement check is completed. What could be rejecting the new connection? Is there a connection limit? Should I just keep my connection open at all time in my application (Open DACS client)? Please advise.
