Problem: SSIS Package Failure Using 32-bit DTExec And 64-bit DTExec

Hi all,


I have a serious problem with my SSIS Package while executing using 32-bit DTExec and 64-bit DTExec.


Here are the details:

Environment:

Windows Server 2003 64-bit (Build 3790: Service Pack 2)
SSIS 32-bit & 64-bit installed
SQL Server 2005 (Microsoft SQL Server 2005 - 9.00.1399.06 (X64) - RTM)

SSIS Package details (compiled in 64 bit)

Script tasks only
Microsoft Visual Basic .NET (using TRY...CATCH block)
PreCompileScriptIntoBinaryCode = TRUE
Run64BitRunTime = TRUE

Execution

Batch file that uses DTExec to execute the Package.

SCENARIO
I am trying to exeucte the above SSIS package using both 32-bit and 64-bit DTExec to make it failure by providing invalid connection string. Here are the details,


Wrong connection String using 32-bit Execution

While establishing the connection the error message has been nicely captured in to my Exception block and writes into the log file.

Wrong connection String using 64-bit Execution

While establishing the connection the error has not been catpured anywhere (although I have TRY CATCH block) and it haults there itself with the message "Process is terminated due to StackOverflowException". Later I found that the error is due to the connection string along with the unhandled exception.

Please suggest any one of the following my findings, also if you have any other advice would be very much appreciated.

1. Shall I go ahead and fix the issue by handling those unhandled errors? (e.g Appdomain, application). I tried several but still not working using 64-bit DTExec.

2. Shall I go ahead and use 32-bit DTExec to execute the package? If so, is there any other major issue...like performance or anyother bug?


P.S: We cannot apply any service pack for SQL Server 2005 at the moment. Sorry abt it. If you have any specific hotfix for DTExec (without affecting SQL Server) then we can decide.

Sorry for the lengthy one and Thanks very much for you help in advance .



Thanks again!
