TLD wildcard doesn't always work

[Chris Michels]

I have been running a DNS server with a top level domain wildcard for
many years now.  It worked fine until I tried to upgrade from BIND 9.2.1
to BIND 9.3.1 or 9.3.2.   Under the 9.3.x versions named returns
NXDOMAIN for some domains.  It looks to me NXDOMAIN is returned for
anything in the edu domain.  Everything else works fine.  Any ideas what
is going on here?

My zone file looks like this:

$TTL 30
;
; zone .
; Bogus root zone for redirecting web requests on some 10.x.0.0 networks
;
@       IN      SOA     garnet.ucc.nau.edu. bogus.nau.edu. 1000001 1800
900 30 30
        IN      NS      garnet.ucc.nau.edu
$ORIGIN .
;
; Default location to send people
*        IN      A      1.2.3.4



And my named.conf lookes like:

#
# named.conf used for redirecting 10.1, 10.2 and possibly other addresses to
# a default web server.
#
# use all default options
options {
       directory "/usr/local/opt/named";
       datasize 25M ;
};

# No hint file since we a pretending to be the root nameserver

#zone "." in {
#        type hint;
#        file "/nau/local/etc/named/named.cache";
#};

# Everything will be defined in the root zone.

zone "." in {
        type master;
        file "/usr/local/opt/named/root.zone";
};
