When you run The Microsoft BizTalk Adapter for the MQSeries Client (MQSC) that is included together with Microsoft Host Integration Server 2013, you experience a decrease in performance over a long time if you receive message data from an IBM MQSeries server.

In a Performance Monitor log, you may also notice a small but steady increase of private bytes.


This problem is caused by a small memory leak that occurs in the BizTalk Adapter for MQSC.
