[Pdns-users] NOTIFY problems

[Mario]

Hi!

I'm running version 2.9.17 (because 2.9.18 have this AXFR problems) and
now I have some problems with NOTIFYs.

My PowerDNS is running as slave DNS.
Since some days I've seen some problems when receiving NOTIFYs from the
masters.

PowerDNS doesn't start the axfr zonetransfer, the logfile only shows:

Oct  3 18:19:01 linux pdns[21941]: Received valid NOTIFY for domain.org
(id=7412) from master 123.123.123.123: 2005100302 > 2005100301
Oct  3 18:19:16 linux pdns[21944]: Received valid NOTIFY for domain.org
(id=7412) from master 123.123.123.123: 2005100302 > 2005100301
Oct  3 18:19:31 linux pdns[21947]: Received valid NOTIFY for domain.org
(id=7412) from master 123.123.123.123: 2005100302 > 2005100301
Oct  3 18:19:46 linux pdns[21941]: Received valid NOTIFY for domain.org
(id=7412) from master 123.123.123.123: 2005100302 > 2005100301

Then the logfile didn't changed for more than 3 hours.

Then I tried the command: pdns_control notify domain.org

After this the PowerDNS restarted:

...

Is it a bug or why did no AXFR zonetransfer started after the NOTIFY?

Ciao, Mario
