PRI0: Upload fails but reports success

[begoldsm]

Upload of a 50gb file is failing, even though no error is returned to the caller. This bug has two issues:

1. There is not enough validation taking place in the upload to properly report success/failure to the caller with confidence
2. Upload is failing consistently, which needs to be addressed and validation for it must be included in future runs.

With debug logs active I see that a lot of transfers are failing, most don't have any error at all associated with them, and some are indicating I/O errors due to accessing closed files (log attached).

This is now fixed and we are seeing sufficient logging to show what is going on.
