SYMPTOMS
In Microsoft BizTalk Server 2004, when a long-running XLANG orchestration is rehydrated, you may receive a NullReferenceException error message. Additionally, the following error message may be logged in the event log:
CAUSE
This problem occurs because changes to internal objects in serialized orchestrations occur after you install hotfix 918758 or BizTalk Server 2004 Service Pack 2 (SP2). When an orchestration is serialized before you install these updates, and then the orchestration is deserialized, the orchestration fails, and a NullReferenceException failure occurs in XLANG.
