One of the Microsoft BizTalk Adapters for Enterprise Applications stops processing incoming messages until you restart the BizTalk Host instance. Additionally, error events are logged in the Application log.
When an error occurs, the adapter maintains a connection to the application that is using the adapter. When the total number of connections that are used by the adapter is equal to the Maximum number of sessions setting in the BizTalk adapter configuration, the adapter cannot process additional incoming messages. The adapter cannot process additional incoming messages because all the connections are being used. An issue occurs because the adapter does not release the connection to the application that is using the adapter.
