Signed 32-bit integer overflow.  After it reaches 2,147,483,647 bytes,
it goes to -2,147,483,468 and counts down.  Many non 64-bit compliant
HTTP clients have this issue.  Even Internet Explorer 6.

But the question is if it is just showing the wrong number, but still
correctly downloading?  Check the filesystem and see if the .part file
is > 2,147,483,647.  If so, then it's probably still downloading the
entire file, the display is just using a signed 32-bit integer value
overflowing.

Either use a newer HTTP client, or use a FTP client.  I prefer ncftp for
a FTP client.  I was able to grab FC5 at 0.5MBps (yes, mega_byte_ per
second) from the fairly close USF mirror (yes, USF is good for something
-- no way!) here in the UCF area.
