One of my team mates reported this problem. He completed a WU and had the collection server dump it, then successfully uploaded the next, and once more had the server dump the third WU. All are P7903.

As a general rule, it's a good idea to report the first error, not the second one. The Work Server failed before the Collection Server did. I would guess that the WU is corrupt.
Why else would it say:
14:43:57:WU01:FS00:Upload 76.98%
14:43:57:WARNING:WU01:FS00:Exception: Failed to send results to work server: Transfer failed
I'm still running v6, so the wording didn't strike me as significant. I've often had WUs fail to go to the work server and end up going to the collection server.
Would you see the same wording if there was a problem with the WS and you had to go to the CS, or does this definitely indicate a problem with the WU/data/upload?
A bad result can be rejected by both a WS and CS and that looks like what happened here, though I'm certainly not sure.
A good WU can fail to go to a WS because the WS is down and then successfully go to the CS. The message about 76.98% does prove the WS accepted part of the WU, which implies the WS was not down.
It's clearer if you look only look at WU01 and ignore the messages about WU00.
