Hello, everyone!
I'm running SSIS package which containing an OLE DB Source, a few Percentage Sampling Transformation components (high on the picture) and the Excel Destination, at the bottom of picture (few different files).

When count of the proceeded rows less than ~400,000, it's running fine, but when rows count goes after ~460,000, Excell destination marked as failed; DataFlow component marked as failed despite it continues executing other flows to the other Excel Destinatons (few Excel Destination in one DataFlow, and data spreading between them due to Percentage Sampling Transformation logic). An other flow continues to execute untill count of proceeded rows with their Excell coming to 460,000; after they fails again.
I has try to use Row Sampling Transformation component instead of this one. When I has tuned it to capture 500 thousand of rows, it would be failed with the package after running, but I tuned it to capture 400 thousand of rows, it would be worked and completed time by time.
It's most horrible that I cannot saw any errors which cause those fails. When I pointed mouse on red icon of error, it doesn't show any message:

It's no any information both in Error windows of Visual Studio

So, let me ask you a question,
- how to determine where bottleneck in my dataFlow (Sample Percentage, or Excell Destination),
- how to view error description of this kind of falis,
- and how to resolve this situation?
At the last thing to talk, there if part of the my dataflow component:
