journal rollforward failed: journal out of sync with zone
Editing zone files without stopping dhcp updates will cause your current zone that you are working to stop working... restarting the process and rebooting have no affect.
If you stop bind and start it with named -g and see the following:
zone somedomain.com/IN: journal rollforward failed: journal out of sync with zone
You saved an edit during an update and the journal became out of sync.
This can be remedied by executing the running the following commands:
rndc freeze somedomain.com rndc reload somedomain.com rndc thaw somedomain.com
If this does not fix the issue, then you can shut down bind and delete the journal it was complaining about.
Finally, you should freeze the zone, edit, reload, and thaw when making changes on a DDNS setup.
rndc freeze somedomain.com
<editor of choice - vi,nano,emacs> somedomain.com and make your changes; then:
rndc reload somedomain.com rndc thaw somedomain.com
