Is bind running as a non root user? If so, is there anything that might be
changing the interfaces so bind can not rebind to them?

Is there anything at all appearing in your bind logs? If not, do you have
the log level cranked up to see if perhaps you could get something?

Configs are a good place to start so folks can take a look at how you expect
your server to start.
