Hi Guys,

I am having an ongoing and painful problem with an SSIS package. The package runs every 5 minutes as an SQL Agent Job and every 2-10 days the package will start running and never stop (thus preventing further executions). If I stop the hung job manually it will begin working perfectly again in the next 5 minute interval.

The SSIS package is for moving data from an Oracle database to a MSSQL 2005 database. It has 7 steps:

• Step 1 calls an Oracle Stored Procedure to prepare the temporary tables inside ORACLE
• Steps 2-6 process the data from the ORACLE tables to the MSSQL tables ORACLE -> MSSQL
• Step 7 calls an Oracle Stored Procedure to clear the ORACLE temporary tables

I suspect that the issue is caused by a communications error between the MSSQL server and the ORACLE server. Both the MSSQL database and Agent/package run on one machine with the ORACLE database running over the network.

I have enabled logging of the SQL package and after more than 2GB of log file I have captured the instant where the package stops responding:

These messages show the entire log generated for the failed run, for a successful run the output is typically ~2500 lines.

I can see that the package is hanging during the initialize operation on the Callista connection (ORACLE database).

I have not been able to work out a way to either fix this issue or have the package die gracefully (an error to the log would be A-OK with me).

Any help or advice would be greatly appreciated.
