SYMPTOMS
Consider the following scenario. The Microsoft BizTalk Adapter for WebSphere MQ (MQSC Adapter) is included in Microsoft Host Integration Server 2006. You use the MQSC Adapter to send messages to an IBM WebSphere MQ queue. In this scenario, excessive duplicate messages may be sent to the WebSphere MQ queue. This problem may occur after the WebSphere MQ queue recovers from an error condition.

Note This problem only occurs if transactions are not enabled.
