DNS error "bad referral"

http://www.acmebw.com/askmrdns/bind-messages.htm

bad referral (state.il.us !<  SOS.STATE.IL.US)
CATEGORY: response-checks
SEVERITY: info
PAGE:
FURTHER INFO:

Indicates that while querying the SOS.STATE.IL.US name servers, your name server was referred to the state.il.us name
servers.  Since a referral should always point to name servers authoritative for descendant zones, this is an error.  The name
server that sent the referral is probably misconfigured, and not authoritative for the zone delegated to it.

my understanding of this is that it is not a configuration error on my part. is this accurate?

Just read the text ...

>  The name server that sent the referral is probably misconfigured,

If your name server produced this message, then it's yours.

the message was contained in the log of my name server. if this is a configuration error on my part then what exactly is misconfigured? my zone files or my named.conf??

thanks

usually your named.conf

Here is my named.conf its pretty simple and was using the same conf file ever prior to the messages showing up in the log.

Any idea where the error is?


// BIND Config File

options {
        directory "/var/named";
        forwarders {198.6.1.195; 198.6.100.25; };
};

zone "xxxxx.com" in {
        type master;
        file "masters/db.xxxxx.com";
        allow-transfer {198.6.1.18; 198.6.1.19;
        137.39.110.20; 137.39.110.134; };
};

zone "yyyyy.xxxxx.com" in {
        type master;
        file "masters/db.yyyyy.xxxxx.com";
};

// Secondary server zone data(client zone info)


// Cache and inverse lookup zone data

zone "." in {
        type hint;
        file "db.named.cache";
};

zone "0.0.127.in-addr.arpa" in {
        type master;
        file "masters/db.127.0.0";
};

Thanks

Explains the bad referral - they have set it up as if it is the root of the DNS namespace when clearly it isn't.
