SERVFAIL from dns server

Dear All,
I have installed and used the caching only dns server for many years,
but after my recent upgrade to FC6 the story is somewhat different.

Any query gives the following error,
Got SERVFAIL reply from 127.0.0.1, trying next server

The second (non local) server resolves nicely.

The named.conf file is fairly simple,

// Config file for caching only name server

options {
directory "/var/named";
listen-on { 127.0.0.1; };
};

zone "." {
type hint;
file "named.ca";
};

zone "0.0.127.in-addr.arpa" {
type master;
file "localhost.zone";
};


Here is the output from /var/log/messages at start,

Mar 11 07:17:21 rafid named[25998]: starting BIND 9.3.2 -u named -t /
var/named/chroot

Any help will be higly appreciated.

Try starting named directly from the command line instead of through the
services intermediary, i.e.

named&

rather than

service named start

and see what happens.

Originally my installation track was

FC6 DVD (xen version of kernel )
Change kernel to the non xen version in DVD
Upgrade to Kernel 2.6.18.8 from kernel.org

I had continuous failure for several days.

Then I tried

FC6 DVD (xen version of kernel )
Upgrade to Kernel 2.6.18.8 from kernel.org


And the problem of SERVFAIL was mystereously solved in the first run.

Any explanation?
