When you receive zombie messages in Microsoft BizTalk Server 2006, you experience the following issues:
This issue occurs because of a problem in the XLANG engine in BizTalk Server 2006. When zombie messages are received in BizTalk Server 2006, the XLANG runtime may treat these messages as if they were not received. This behaviour causes the instance to dehydrate. Then, the messages are routed to the orchestration instance again. This causes the instance to rehydrate. However, the messages still cannot be processed. Therefore, the orchestration instance continuously dehydrates and then rehydrates. This behavior causes high CPU usage on the BizTalk Server 2006 instance. Therefore, this issue affects the performance of the computer that hosts BizTalk Server 2006.
After you apply this hotfix, the zombie messages are suspended before the cycle of dehydration and rehydration begins.
