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, Edda
