SYMPTOMS
In Microsoft BizTalk Server 2004, you may experience a decrease in performance as measured by the number of documents that are processed per second. When you use a long-running orchestration, such as a singleton orchestration, BizTalk Server performance may decrease over time.
This problem may occur when the following conditions are true:
- A long-running orchestration has some transactional or non-transactional scope inside a loop.
- Messages are received in the scope.
Additionally, the BizTalkMsgBoxDb database may grow very large.
