Hi,
I have been using this patch in production for a higly loaded network for over
2 weeks now.
2 realservers running dnscache and tinydns.
(I had to apply a patch to dnscache from dnscache.org so it can listen on the
real server's ip since it will only listen on one ip to which it is
configured - normally the VIP)
Respectfully,
