So if I understand correctly, the script works well on
smaller files but not on the large one?

_Which_ line is never reached? The `print` statement after
the `retrbinary` call?

Can't you reproduce the error by executing the script once
more? Can you copy the file to another server and see if the
problem shows up there, too?

I can imagine the error message (a full traceback if
possible) would help to say a bit more about the cause of
the problem and maybe what to do about it.
