What does error 0xC02020C4 mean in SSIS?

Question

I get this error with this description. Error: SSIS Error Code DTS_E_PRIMEOUTPUTFAILED.
The PrimeOutput method on component "OLE DB Source" (1) returned error code 0xC02020C4. The component returned a failure code when the pipeline engine called PrimeOutput(). The meaning of the failure code is defined by the component, but the error is fatal and the pipeline stopped executing. There may be error messages posted before this with more information about the failure.

Answer 1

I believe that the associated error message is "The attempt to add a row to the Data Flow task buffer failed with error code 0x{%errCode2}." Which should have been in a previous log message. Of course then you will want to get %errCode2, and translate it to an error message that should have been even earlier than that in the log messages. This could go back a ways.

The easiest approach is to turn all of the logging on, run it to the failure and the check the logs going backwards until you find the original generating exception.
