  That's the issue.  The original request has timed out, and has been
removed from the list of outstanding proxied packets.

  RADIUS isn't perfect.  If a request takes too long, the client can
give up on it.  When the home server finally responds, the proxy
discovers that there is no place for the response to go.

  Because there's no reason to do that.  In fact, the only thing that
the proxy can do is to discard the response.

  Make sure that the home server (and the proxy) process packets in a
timely manner.
