Looks OK. Can you post your named.conf? (or mail it privately)

Hmm. Any evidence why it stops? Core dump file? What sort of machine is it?
Have you upgraded to the latest bind? Are you sure you haven't been hacked?
(Some old versions of bind had big security holes which were widely
exploited across the Internet)

It may be worth reinstalling this machine from scratch.

It might also be a hardware problem. Do you ever see "signal 11 -
segmentation violation" when the machine is busy, e.g. compiling a large
piece of code? This usually indicates a RAM fault.
