Handling all exceptions AND Failed Messages in a BizTalk 2010 solution

I have a BizTalk 2010 solution that polls a database table, retrieves unprocessed records, does a transform with a map and call a 3rd party service. The happy path is working.

Here is the workflow:

1. Receive Location/Port from GetUnprocessedCustomers stored procedure: Poll SQL Server 2008 with WCF-SQL adapter by calling stored proc that returns unprocessed customers (WHERE IsProcessed = 0)
2. SendPort to 3rd Party web service: Filtered to ReceivePortName == with an outbound map to convert message returned from the above mentioned stored proc to service schema
3. SendPort to UpdateIsProcessed stored proc: Filtered to MessageType == with an outbound map to convert service response to stored procedure call that will update IsProcesse开发者_StackOverflow社区d = 1.

I would like to catch the following possible exceptions, create a message with exception info and call an internal exception handling service.

1. Database or stored procedure is not accessible.
2. 3rd party service is not accessible.

I was able to handle number 2 above by enabling Failed Message routing. Thanks to Greg.Forsythe.

My question is: How can I create a generic solution that will capture all exceptions and send exception info (such as exception datetime, message, stack trace etc.) to an internal service?

I was able to get an answer on the BizTalk General Forum. The short answer is "There is no way to catch all exceptions". Hit the link for some options.
