FreeBSD by default has a constant (it's in one of the header files) that limits to 256 file descriptors. If you compile bind with a larger descriptor it works fine. Took me a few hours to track that one down in the debugger. One of our clients has a lot of scripts that depends on 4.9's config. file syntax so 8.x wasn't an option at the time.
