I haven't run in to that, but something to check is whether your installation of BIND was built with response rate limiting. The FreeBSD port has it enabled by default, but it is a selectable option.

Two quick ways to check:
% pkg info bind910|grep RRL
	RRL            : on

% named -V
built by make with [...] '--enable-rrl' [...]
