Version is reported as "PowerDNS Recursor 3.1.4 $Id: pdns_recursor.cc 917 2006-11-07 12:23:51Z ahu $" In the meantime our customer has fixed the NS rrsets of zone bsz-bw.de, so the problem can no longer be reproduced. The different default TTLs of the two masters have not been corrected. Peeking at the cache dump, I now see bsz-bw.de. 5414 IN NS dns1.belwue.de. bsz-bw.de. 206 IN NS dns1.belwue.de. bsz-bw.de. 5414 IN NS dns3.belwue.de. bsz-bw.de. 206 IN NS dns3.belwue.de. bsz-bw.de. 5414 IN NS uranos.rz.uni-konstanz.de. bsz-bw.de. 206 IN NS uranos.rz.uni-konstanz.de. Basically, the screwed setup was: Master A announces: $TTL 86400 example.com NS B example.com NS X example.com NS Y Master B announces: $TTL 43200 example.com NS A example.com NS X example.com NS Y Slave X uses Master A Slave Y uses Master B Regards, -Juergen _______________________________________________ Pdns-users mailing list Pdns-users@mailman.powerdns.com http://mailman.powerdns.com/mailman/listinfo/pdns-users
