checkhints: unable to get root NS rrset from cache: not found

[Peter Davies]

Hi Marc,
        I loaded a new version from the net same time I upgraded bind .
 When I started receiving the checkhints warning I remove the ip6 entries 
- but that didn't help.
Here's the content of the hints file minus comments

                 What do you have in your hints file?

                 What do you get if you run "dig ns . @<address>" where
                 <address> are the addresses in the hints file.
