You were mentioning a different ticket number...

Anyway, you seem to be waiting for the first
storeFile deferred (Consumer) to indicate successful
transmission, I'm using the second (Control-Connection),
maybe you simply quit to early.

If you want, I can mail you my FTP access class
for uploading and downloading....
