Dear mr Schacher, This is an effect of the packet cache, which indeed does not take max-negative-ttl into account, nor does it respond to 'rec_control wipe-cache'. It is really fast however. For now, you could solve this problem by setting packet-cache-ttl to a lower number, say 20 seconds. Can you also open tickets on http://wiki.powerdns.com (login with the password NoSpam) about this problem? 1) packet cache does not do max-negative-ttl 2) wipe-cache ignores the packetcache Thanks! > > If we restart the recursor, the new records show up immediately. > Could you give me any hints on what could be wrong here? > > > Thanks in advance > Oli > _______________________________________________ > Pdns-users mailing list > Pdns-users@mailman.powerdns.com > http://mailman.powerdns.com/mailman/listinfo/pdns-users > _______________________________________________ Pdns-users mailing list Pdns-users@mailman.powerdns.com http://mailman.powerdns.com/mailman/listinfo/pdns-users
