You have datasize (hard limit) and max-cache-size (soft limit)=20
both set to 20M. datasize is there to raise the default limit
if it is too low. max-cache-size is there to restrict the
amount of memory used by the cache.
datasize should be greater than max-cache-size or you will
always
hit the hard limit before you hit the soft limit which lets
named
start cleaning out old cache entries.
