We discovered yesterday that adding the following routes,
which are present in: /etc/rc.d/network_ipv6, but not
active unless ipv6_enable="YES" is set fixed the issue:-

route add -inet6 ::ffff: -prefixlen 96 ::1 -reject
route add -inet6 :: -prefixlen 96 ::1 -reject

I haven't confirmed but this is reported to be set
by default on 9.x due to the changes in rc.d scripts.
