Symptoms
Assume that you use MQSeries as a send adapter and use XML Validator in a send pipeline in Microsoft BizTalk Server 2010. When a message is not validated successfully at the XML Validator, the message remains in "Active" state instead of the expected "Suspended" state. Additionally, you receive the following error message in the event log:
The adapter "MQSeries" raised an error message. Details "The element '<Element Name>' has invalid child element '<Child Element Name>'. List of possible elements expected: <Expected Name>'."
Note MQSAgent.dll on the IBM WebSphere MQ server must be updated to the same Cumulative Update (CU) level as on BizTalk Server. To do this, make sure that you run the same CU setup on the IBM WebSphere MQ server. You may experience performance issues if you run mismatched versions.
