Hi Peter,

got it. I started returning END as you have suggested. But my problem is
still not solved.

Suppose i have CNAME record -> example.com      CNAME      cname.example.com.
So when pdns queries for example.com, the backend returned cname.example.com

The following are the queries pdns asked the backend and the replies i

example.com                  ANY             -             example.com
 CNAME          cname.example.com
cname.example.com       SOA             -             END
com                               SOA             -             END

At this point, pdns is going into a blocked state. Its not replying
anything to the dig command.
Can some one suggest what might be the reason?

One solution can be returning just END which is little hacky. i was wondering if there is any other way to prevent pdns from querying the backend for resolving the CNAME.*
