I don't remember seeing that, and in fact all I can find in "DNS and
Bind" is (from page 181):

"When you need to create new name servers for your domain, the simplest
recourse is to add slaves. You already know how--we went over it in
Chapter 4--and once you've set one slave up, cloning it is a piece of
cake. but you can run into trouble indiscriminately adding slaves.

"If you run a large number of slave servers for a zone, the primary
master name server can take quite a beating just keeping up with the
slaves' polling to check that their data are current."


It doesn't seem logical that only three slaves would cause this kind of
problem, so I doubt that's a limitation.

As I recall the ISP Consortium (www.ispc.org) has more than three slaves
available to members who take advantage of their secondary DNS service
for members.
