Suggested solutions

  1. Add more physical memory to the computer
  2. Reduce the number of parallel SSIS package execution
  3. Exit applications that consume lots of memory when you run the SSIS 2008 package that contains dataflow tasks
  4. When you run the SSIS 2008 package, set the Maximum server memory option for the SQL Server 2008 instance to a smaller value. This behavior increases available memory
  5. Run the SSIS 2008 package on a computer that is not running an instance of SQL Server
