The error is being thrown by an orchestration during the processing of a message obtained from an SQL table.

The data was obtained successfully because I have a readingIndex that's updated by biztalk.

The problem happens randomly, but I can fix it by restarting the biztalk application.

What could possibly be causing the problem?

Do I reset some identification code by restarting the applications?
