I haven't been tracking this since it started out because so many eyes
jumped right to it.  Peter, is this an example of the problem you are
seeing,  random connections to apache running on 80 don't connect, but
if you try to connect right back the, connection succeeds ?

We had a problem just like this a few months ago but it was related
somewhat to our handling of IPv6 packets ver's IPv4.  I wonder if that
could still be the case.
