DNS Zones not working after OS X 10.8.5 upgrade
Ah... I figured it out...

"named-checkconf -z" returns

zone localhost/IN: loaded serial 42
zone 0.0.127.in-addr.arpa/IN: loaded serial 1997022700
dns_rdata_fromtext: dev.zone:5: near '090712070736': out of range
zone dev/IN: loading from master file devcs1.zone failed: out of range
zone dev/IN: not loaded due to errors.
_default/dev/IN: out of range


Evidently my serial number is invalid... it should be YYYYMMDDNN (where NN is any number between 00 and 99). I changed the serial to "2013092001" and it's working fine.

Evidently the new version of Bind is more strict about serial numbers than the previous version.

You can use the following to tell what version of bind you're running:

nslookup -q=txt -class=CHAOS version.bind. 0


OS X 10.8.5 ships with Bind 9.8.5-P1.

OS X 10.8.4 shipped with 9.8.3-P1

Hopefully that helps someone else down the road.
