On a computer that is running Microsoft BizTalk Server 2009, you have Microsoft BizTalk 2009 Accelerator for HL7 installed.
You create and deploy a BizTalk Server 2009 application to receive and process HL7 messages.
BizTalk Server 2009 receives lots of messages of reasonable size. For example, you receive thousands of messages, each with the size of 7 kilobytes.
In this scenario, the memory usage of the BizTalk Server Host Instance increases significantly. This behavior causes host throttling, and slows down the processing of messages.
This problem occurs because of an error in the pipeline component of BizTalk 2009 Accelerator for HL7.
After you apply this hotfix, BizTalk Server 2009 processes HL7 messages more quickly.
