Inconsistant use of views. The NOERROR will probably be coming from a the internal view and the NXDOMAIN from the external view (or the other way around). As for SERVFAIL you may have badly configured firewalls that are dropping fragmented responses, or responses > 512 bytes resulting in excessive timeouts and excessive use of TCP. This is more visible in a newly started server.
