Actually I reckon it should be one match not more. What are the matches?

That indicates a bug in the data-source plugins (if catching is enabled
the cache should return the hit and not pass it through the db plugin).

Can you please fill a stacktrace to which parts are requested twice, we
need to find out where the caching is failing.
