	I would say that machine is under resourced for the load
	you are putting on it.

	Now you havn't told us what version of named you are running.
	What OS this is on.
	Whether it is a authoritative server, caching server or both.
	You also havn't said what the working set size of the process
	is (ps will tell you this).
