A DNS server which is supposed to be authoritative for a zone, but isnt.
in your BIND logs, then BIND has queried a lame server. In this case, 62.119.40.115 is mentioned as being authoritative somewhere for the zone 98.96-27.40.119.62.in-addr.arpa, but when BIND queries it, it discovers that 62.119.40.115 is not authoritative, and logs that message. The SysAdmin at the other end needs to get a clue and fix his DNS.
If you are an administrator and got tired from all these messages in your logs, you can easily disable this "lame server" logging once and for all. Just add the following directive in your /etc/named.conf (or whereever your named.conf is on your machine):
logging {
category lame-servers { null; };
};
That's it.
