<br>
On secondary dns server, the configured zone files are created then <br>
written every 3600 seconds (by default).<br>
These files are not written on zone update received from master.<br>
Maybe I'm missing something, but I imagine nsd can load these zone files <br>
and serve records (as long as records are not obsolete) even if the <br>
master server is unreachable.<br>
So, to avoid serving obsolete zone data it may be a good idea to update <br>
zone files as soon as an update incomes.<br>
Is there any option to do that in nsd ?<br>
