Michael,

  I remember this problem from the last time Hal mentioned it, I had
just forgotten about it. I'm almost certain this is being caused by
a reference counter incremented in the sdp address resolution code
that is never decremented. In sdp_link.c:do_link_path_lookup() we get
the route table entry using ip_route_output_key(), which I believe
takes out a reference, and that reference should be returned using
ip_rt_put() which we never do.
