Today, when I was working on SSIS packages, I got an error which as often in SSIS is not clear and descriptive. I searched online for the description and explanation and found this link in MSDN. http://msdn.microsoft.com/en-us/library/ms345164.aspx
The page contions all messages in SSIS (be it Error or Warning or Informational etc). It contains the error cumber and what does it mean.. Hope it helps you too in finding the explanation/ description for your error/ warning code.
