A fault message is generated by the following call to the BizTalk ESB Toolkit API:
The resulting fault message captures the error type identifier. This message could reach a length of more than 100 characters. When this message is submitted to the EsbExceptionDb database by the Microsoft.Practices.ESB BizTalk application, an exception is thrown by the computer that's running SQL Server.
This issue occurs because the size of the ErrorType and ExceptionType columns in the Fault table of the EsbExceptionDb database is limited to 100 characters in BizTalk Server.
