Error: already exists previous definition

Hi

We have getting a lot of errors like the following from our BIND 9
servers (9.5.1.1):

20-Jul-2012 15:26:40.181 config: error:
/var/named/etc/namedb/conf/zone_0.conf:1529: zone 'xxxxx.net':
already exists previous definition: /var/named/etc/namedb/conf/zone_0.conf:1529
20-Jul-2012 15:26:46.270 general: error: reloading configuration
failed: failure

This has never ever happened before and the problem only started a
few days day, and we did not make any changes to our BIND servers. In
fact, we have using the same set up and configuration for over 3
years without any problem until now.

The puzzling aspect is, there is NO duplicated config or zone entries
at all for the domains listed in such error. In this instance, this
is the only line found in zone_0.conf:

zone "xxxxx.net" {type master; file
"/var/named/etc/namedb/zones/0/xxxxx.net"; notify no; };

I will appreciate greatly if someone could offer any advise or idea
as to what's exactly causing such errors? Thanks vert much.

Regards,

Tom

Are there any duplicate include directives?

That you remember or someone is honest enough to admit to.

The error looks like you have included a configuration file twice.

Hi

No, there's no duplicated directives in the zone file. For example, here's the zone for another domain with the same error and here are the only directives:

$ORIGIN xxxxx.com.
$TTL 3600

That looks very suspiciously like a file which has been included twice.
Check again. And again. :)

Are you quite sure? What are the modification times of named.conf and
*all files* it includes? [ls -l]

What does `named-checkconf' report?

Oh, and while you're at it, you should upgrade BIND -- the version you
are using is pretty old.
