The user in question is using some kind of download accelerator that
uses multiple byte-range requests to access the same file
simultaneously over multiple connections.  In general, these
accelerators are designed simply to squeeze out other users and hence
get faster downloads.  It should be considered and handled like a
denial-of-service attack.  Some documentation on that is here:
http://httpd.apache.org/docs/trunk/misc/security_tips.html#dos

In general, either use a firewall to restrict number of connections
per IP, or use a third-party module to do the same.  See
http://modules.apache.org/
