Why, I hardly even know you! Or, did you perhaps mean "bear" instead of
"bare"....?

It would appear that you forgot to dot-terminate the contents of the
MNAME field ("origin") of your SOA record. While I can't be sure that
this is the root cause of your problem, it's certainly not helping. Try
dot-terminating the name and see if it works better.
