Subsequent tests showed that it looped every time.  Restarting just
postponed the behavior.

Only three IP entries.  The last one was a CNAME.  Changing them
thusly fixed the problem:

	# diff whiteclnt~ whiteclnt
	< ok    ip      localhost
	<       ip
	<       ip
	> ok    ip
	> #     ip
	> #     ip

I don't know which of the three caused the problem.
