I share with you a problem I had recently on SSIS.

Problem Description: When you start treatments in parallel, your SSIS packages fail error. You have two servers and one reproduces this behavior.

You got the following error: Attempted to read or write protected memory. This is often an indication that other memory is corrupt.
Cause: We initially verified that the versions of drivers were exactly the same on both servers.
- The server with the issue was in  DataAccess64 Sybase build
- The server without the issue was in DataAccess64 Sybase build

Resolution: We have copied only directories DataAccesset DataAccess64 Sybase client (build to the client installed (build

The problem has been fixed with this workaround.

If you can not fix your problem I invite you to generate a dump, then call MS support.
