BIND9: one zone is not up to date

[Roberto Carna]

Dear all, I have BIND 9 and Webmin. One master and one slave using zne
ransfer with TSIG

Everything was Ok till today.

When I add or modify a record for zone1.com in the master, the record
in the slave is up to date.

But when I add or modify a record for zone2.com in the master, the
record is not updated in the slave, however the log in
/var/log/bind/bind.log tell me the update operation was OK:

13-Dec-2021 14:46:24.558 notify: info: client @0x7fe8ec5532f0
172.17.1.2#56011/key xxx: received notify for zone 'zone2.com': TSIG
'xxx'
13-Dec-2021 14:46:24.558 general: info: zone zone2.com/IN: notify from
172.17.1.2#56011: zone is up to date

What can be the problem? I see everything well defined.

Special thanks !
