What probably happened is that caching nameserver tried multiple times
(because they got no answer) and tried again for every query they got
themselves.

Putting this in your data file could help:

&::a.root-servers.net

This tells everybody that asks you about zones you don't have to go ask
the A root server. Not perfect but surely better than the default behaviour.
