When checking the BIND XML statistics I see the following in the "Cache DB
RRsets" section, which I think
could be the reason for the high memory usage:

!AAAA   18446744073709551559
!A6     18446744073709551607

Is this an overflow on the counter for these negative responses in Cache, or
could there really be that many objects in the cache ?

Assuming these were output as uint64_t but then reinterpreting them as
int64_t, they are very *small* negative numbers, -57 and -9 respectively.
I suspect something other than overflow is responsible.
