Thank you, that clears the situation. I was very surprised about
this behaviour.

We have a lot of customers with master servers for their own domains, not
every server is bind 9 or even bind. The notify mechanism doesn't work
well on all these servers. With bind 8 we simply send a kill -HUP
to our slave and it starts reloading all updated zones. With bind 9
we observe that our slaves get some updates only after the refresh time
is expired.

Thank you again,
