I have a linux machine configured with the powerdns server 3.0rc2 as an authoritive server using the gmysql backend. This server is configured to handle recursive queries for the local campus as well by handling the request over the recursive resolver.
The issue that I am seeing is that the first time a request is handled over to the recursive resolver (ie www.news.com), I get the correct results for the query. Then if I duplicate the query again before the timeout of set by the recursive-cache-ttl expires, I get the following error when using nslookup: Non-authoritative answer: *** Can't find www.news.com: No answer When using dig, the result that I get back when it doesn't resolve is: ; <<>> DiG 9.8.0 <<>> www.news.com ;; global options: +cmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 4227 ;; flags: qr rd ra; QUERY: 1, ANSWER: 0, AUTHORITY: 0, ADDITIONAL: 0 ;; QUESTION SECTION: ;www.news.com.

Is there some setting I am missing for allowing access to the recursive-cache or is this a bug? Thanks! Steve
