SYMPTOMS
In Microsoft BizTalk Server 2006 or in Microsoft BizTalk Server 2004, you use Microsoft BizTalk Adapter for MQSeries to process messages from an IBM MQSeries server. When you do this, the BizTalk application may slow down, and the BizTalk application may eventually stop responding.



CAUSE
This problem occurs because a memory leak occurs in the default memory heap when you use BizTalk Adapter for MQSeries. This problem occurs when the message that BizTalk Adapter for MQSeries receives has no context properties. Therefore, BizTalk Adapter for MQSeries does not initialize the internal structures correctly.
