Consider the following scenario in Microsoft BizTalk Server 2006:
If the correlating message is not received within the time-out value that is specified and if the TimeoutException exception is thrown, the Microsoft BizTalk Server XLANG Scheduler Engine enters an infinite loop. This causes 100 percent of the CPU resources to be used. Additionally, the start orchestration shape in the exception handler of the non-transactional scope will not be hit.
This problem occurs because the long-running transaction scope has special logic to handle time-out exceptions. However, the TimeoutException exception is not correctly handled by the non-transactional scope.
