I just uploaded a new batch of records for a domain into my PowerDNS database (MySQL).
My primary name server (ns1), for some reason, is returning nothing for one particular record where the secondary (ns2) does. It works for the other records. It appears that the primary server ns1 is misbehaving. From my workstation: $ dig @ns1.mydomain.com foo.bar.com Correct record returned. $ dig @ns2.mydomain.com foo.bar.com Correct record returned. From primary server: $ dig @localhost foo.bar.com ;; connection timed out; no servers could be reached From secondary server: $ dig @localhost foo.bar.com Correct record returned. On the primary server: If I restart PowerDNS, /var/log/messages says: Jun 14 20:52:23 ns1 pdns[2614]: Scheduling exit on remote request Jun 14 20:52:23 ns1 pdns[2614]: Guardian is killed, taking down children with us Jun 14 20:52:26 ns1 pdns[3925]: Listening on controlsocket in '/var/run/pdns.controlsocket' Jun 14 20:52:26 ns1 pdns[3927]: Guardian is launching an instance Jun 14 20:52:26 ns1 pdns[3927]: This is a guarded instance of pdns Jun 14 20:52:26 ns1 pdns[3927]: UDP server bound to XXX.XXX.XXX.XXX:53 Jun 14 20:52:26 ns1 pdns[3927]: TCP server bound to XXX.XXX.XXX.XXX:53 Jun 14 20:52:26 ns1 pdns[3927]: PowerDNS 2.9.21.2 (C) 2001-2008 PowerDNS.COM BV (Nov 16 2008, 14:07:43, gcc 4.2.3 (Ubuntu 4.2.3-2ubuntu7)) starting up Jun 14 20:52:26 ns1 pdns[3927]: PowerDNS comes with ABSOLUTELY NO WARRANTY.

Any ideas on how to diagnose this troublesome server?
