Symptoms
When you use one of the following adapters that are included in Microsoft BizTalk Adapter Pack 2.0 or in Microsoft BizTalk Adapter Pack 2010 on a receive location, the receive location restarts unexpectedly:
-
The Windows Communication Foundation (WCF)-SQL adapter
-
The WCF-Oracle adapter
Additionally, BizTalk Server may encounter the ConnectionException exception, and then the BizTalk server may restart after one of the following warnings is logged in the Application log.

Cause
This issue occurs because the receive location restarts unexpectedly when the WaitForMessage method generates a TimeoutException exception.
When the WaitForMessage method generates a TimeoutException exception, the TryReceive method is called, and then the WCF-SQL adapter or the WCF-Oracle adapter rolls back the transaction. However, the rollback operation may generate an ObjectDisposedException exception. Therefore, one of the warnings that are mentioned in the "Symptoms" section is generated.
