	Normally I restart it when I upgrade named or reboot the
	server.  This has been true since the cache cleaning code
	was introduced.  Since that time named has stablised its
	memory usage after 7 days.  This has been true since BIND
	4.9.3 when I added cache cleaning.

	Yes, I've run named processes for months without restarting.

	The cache size is dependent upon the workload being put on the
	server.  If the cache is growing "to big" the server is under
	resourced for the load on it.
