I caused this myself I believe but I'm wondering why. I'm having issues
getting named to work correctly in chroot configuration, it will run but
when started reports zone files not found even though they are where I
have them in the named.conf file. So, I stopped named running and went
back to the OpenDNS nameservers in my resolf.conf file. The outcome is
above. Can someone enlighten me as to why this happened since I had
named stop and was not using 127.0.0.1 as the local caching nameserver.
Also, if anyone could possibly lend me a hand with this running named
chrooted I'd appreciate it. Please contact me off list. After starting
named again all seems back to normal with SA.

man 2 sendto

  [ECONNREFUSED]     The socket received an ICMP destination
         unreachable message from the last message sent.  This typically
         means that the receiver is not listening on the remote port.

Your DNS server is not reachable - either it is not running, or
is being blocked by a firewall, or your <chroot>/etc/resolv.conf
is misconfigured.

Are they in the path listed in named.conf or are they in
/<chrootdir>/<named.conf path>.

They need to be in the latter. ie: if named.conf says
/var/named/zones/zonefile.zone and you're chrooting to /var/named it
will actually try to read /var/named/var/named/zones/zonefile.zone,
because / has been replaced by /var/named.

Sounds like you have a firewall somewhere (local iptables/ipfw? or
perhaps a dedicated firewall device) that's refusing the traffic.
