The zones have different numbers of nameservers.

Your nameserver notifed one other nameserver, which had one A record
associated with it.

Your nameserver notifed two other nameservers, which had one A record
each, giving a total of two. If one of the nameservers was multihomed
you would see the A number higher than the NS number.

The answer packet received in response to the NOTIFY didn't have the AA
bit set. It should. This is a bug in versions before 8.2.3-REL. Your
8.2.3 nameserver is logging that FYI.
BTW, that means your slave isn't running 8.2.3-REL. Versions of BIND
before 8.2.3 have serious security vulnerabilites. It should be upgraded
ASAP.
