	I suspect it is a bit of both.  You have TTLs of 5 minutes
	which is causing the caches to continually go back to the
	parent zones.  They most probably are running old versions
	of BIND 9 that have to timeout on the IPv6 addresses of the
	COM/NET servers.

	The timeout problem is fixed (except for one OS and we are
	working with the OS manufacture to address the problem, the IP
	stack needs changes made to it) as of BIND 9.2.5 / BIND 9.3.1.
