SYMPTOMS
In Microsoft BizTalk Server 2004, the performance of a singleton orchestration may decrease over time, as this performance is measured by the Document Processed Per Second performance counter. This problem may occur if the following conditions are true:
 * The singleton orchestration calls another orchestration inside a loop by using the Call Orchestration shape.
 * The singleton orchestration passes a message parameter to the called orchestration.
 * The called orchestration is non-transactional.
