BIND 9.2.4 NOTIFY problem from Master

Thanks Cathy. I'll post my question to bind-users.
Anthony Iliopoulos was very helpful. He suggested I use the notify category in our logging channel statement. We can now see that the secondaries do receive notification from the master. We just have to figure out why the secondaries don't act on this notify.

bind-users is a better list for this type of 'why' and 'how to' discussion.
BIND 9.2.4 is very old and no longer supported by ISC - we'd recommend
that you upgrade to something current in order to obtain the latest bug
fixes, features and protection from security issues. I don't recall
offhand if there are relevant changes - but you can check this yourself
by looking in the release notes for newer versions.
Unless you disabled notify or changed how/who is notified in the
configuration, by default a nameserver loading a zone is going to notify
all the authoritative servers per the NS records found in the actual
zone that is loaded. The one exception to this is the primary master
(as found in the SOA record for the zone).
If this doesn't help provide clues, please can you re-post your question
to bind-users - (noting that the community there will also most likely
advise you to upgrade your version too!).
