IPv6 TCP

I posted this query a while ago but have not yet been able to resolve the issue...

I have a DNS server and client that can ping each other using ping6.  The following query works:

dig -6 test.com +notcp 

When I query TCP with IPv6 I get the following error:

root at test:/home/janderson/bind-9.6.1-P1 dig -6 test.com @bind6 +tcp
socket.c:4922: 22/Invalid argument
dig: isc_socket_connect: unexpected error

The query never leaves the client so the server never logs anything and I get the same result if I issue the dig command from the client or DNS server.

Config details follow

O/S => RH 5 64-bit
root at test:/etc uname -a
Linux test 2.6.18-164.2.1.el5 #1 SMP Mon Sep 21 04:37:42 EDT 2009 x86_64 x86_64 x86_64 GNU/Linux

BIND Version - version: 9.6.1-P1 

Configured with the following options:
built with '--enable-threads' '--with-openssl=/usr/local/ssl/bin' '--enable-ipv6'

named.conf options
options {
        directory "/var/named";
        version none;
        recursion yes;
        allow-recursion { 10.10.10.0/24; };
        listen-on { 10.10.0.1; };
        listen-on-v6 { aa10::b214:4cdf:ad7d:12a; };
};

Thanks!!
