The primary server does not send notify information
Summary
My primary bind server needed to synchronize 13 zone files to 3 secondary servers, but 1-2 zone synchronization was missed each time. I found through logs that the primary bind did not send notify information to the secondary server. But one solution I have is to execute rndc reload twice every time you modify the zone file to synchronize it all. What's the problem?
