	The problem is very simple.  BIND 4.9.3 is so old that it
	doesn't treat the "CNAME and other data" error as fatal.
	BIND 9 refuses to load the zone as it has a "CNAME and other
	data" error.

	Googling for "CNAME and other data" will give you hundreds
	of pages explaining the problem.

	The fix is to remove the "CNAME and other data" error from
	the zone.

	The simplest way to prevent this occuring again is to upgrade
	the master.  It is grossly out of date.
