  You should really upgrade to 3.2.1.

  HUP only reloads a few things.  It's just too hard to reload clients and home servers on the fly.

  3.2.1 has some provisions for reloading home servers dynamically.  But you can't just HUP the server, it's more complicated than that.  See raddb/home_servers/ in the 3.2 distribution.
