``datasize``
   This sets the maximum amount of data memory the server may use. The default is
   ``default``. This is a hard limit on server memory usage; if the
   server attempts to allocate memory in excess of this limit, the
   allocation will fail, which may in turn leave the server unable to
   perform DNS service. Therefore, this option is rarely useful as a way
   to limit the amount of memory used by the server, but it can be
   used to raise an operating system data size limit that is too small
   by default. To limit the amount of memory used by the
   server, use the ``max-cache-size`` and ``recursive-clients`` options
   instead.
