well, you are helping me...

The bad news is that "debug_options ALL,9" caused test upload to succeed
(multiple attempts). After commenting it out it fails again.

and that was single transaction.

I founbd out that with:

debug_options 33,9

- mostly succeeds, sometimes crashes.

however the "* We are completely uploaded and fine" message is new here
(but doesn't appear all the time)

I also tried 9,9 without success.


Could errors like this be caused by something like lacking fflush() on socket?
