Yes. Consider a very huge zone which gets updated with IXFR every few seconds. That would be heavy to write the zone to disk after every update. > Is there any reason why updates aren't > written as soon as the file they are replacing is older than 1 hour? AFAIK this is actually the case, when default zonefile-write=1h In my opinion, it would be useful to have a zonefile-write-onshutdown=true option to force a "write" when the daemon is shut down. I think this is what Bind9 for example does. regards Klaus _______________________________________________ nsd-users mailing list nsd-users@lists.nlnetlabs.nl https://lists.nlnetlabs.nl/mailman/listinfo/nsd-users
