By default named will send notifies to all name servers listed in the NS 
RR set for a given zone, except for the name server listed in the dname 
field of the SOA RR, regardless of whether named loaded the zone as a 
master or slave.  This behavior is driven by RFC 1996.

You probably don't want the slave(s) sending the notify.  Use the 
following zone syntax to turn this behavior off:

zone ""{
        type slave;
        file "";
        notify no;

Notice the use of "notify no;".  This statement turns off notify for this 
zone.  Read the BIND ARM for details regarding other notify tweaking 
features such as "also-notify" and "notify-source-..."
