Force slave BIND9 server reload inmediately

[Arturo Díaz Almagro]

Hello all,
Hope anybody could help me. I have two BIND9 servers where one is the master
and other is the slave. I realized that when I perform a change in a zone
file in the master and reload/restart the master BIND9 service the slave
does not start the zone transfer inmediately. I have a 'high availability'
system where the DNS server has an important role and I need those changes
inmediately loaded. I noticed that those changes are loaded but in a big
period time, so the system replication works. Could anybody tell me how to
force BIND9 to load changes inmediately after the notifies are received?

Thanks a lot.
