Let me guess, you've got IP Masq running somewhere on your link?

FTP uses two connections, one for control messages, one for data. When
you are downloading something it comes over the data connection, whilst
the control connection is idle.

The problem comes about when you mix this with IP Masq, which drops
connections when they have been idea for a certain period of time.
I'm guessing by now you can already see the problem? :)

Small downloads will work (they will complete within the timeout period).
Large downloads will have the control channel closed during the transfer,
which with Netscape causes exactly the symptoms you're seeing - it gets to
100%, tries to use the control channel to confirm the download has
completed, and dies/hangs.
