ods-signer crash due to missing intermediate zone

Hello,

The ods-signed daemon crashed consistently when it tried to reload a zone. It's last words were

Mar 26 19:23:26 dnsmaxi ods-signerd: +RR example.com. 3600 IN DNSKEY 257 3 8 blah ;

{id = 56549 (ksk), size = 2048b}

Mar 26 19:23:26 dnsmaxi ods-signerd: +RR example.com. 3600 IN NSEC3PARAM 1 0 5 3d125b405a3a4b2d
Mar 26 19:23:26 dnsmaxi ods-signerd: [data] +DD : _udp.example.com.
Mar 26 19:23:26 dnsmaxi ods-signerd: signer/rrset.c:157: rrset_recover: assertion flags failed

From what I can understand in the code and this exception, it is trying to recover a zone (+DD) that does not exist in the zone, namely _udp.example.com. The zone example.com does have a RR for _sip._udp.example.com. which is an SRV record for SIP.

I removed the zone, did ods-control stop/start, then added the zone once more. This time there were no problems. If I find a more consistent recreational pattern I will extend this report, sorry.

But let me know if I need to dig up more information – or of course if this could be my own wrong.

Cheers,
-Rick
