Description Fabrice Bellet 2017-07-17 11:44:40 UTC 
It seems that ddns updates are no longer performed by dhcpd since its been rebuilt against bind99 9.9.10. From my experience, it comes from the function dns_client_startupdate() that slightly changed since 9.9.9 : in the newer version, a call to isc__app_ctxonrun() returns error 35 (already running) instead of calling startupdate() where the code has been moved to.

Comment 2 Pavel Zhukov 2017-07-17 15:17:36 UTC 
Thank you for reporting the issue. 
Bind is moving to use application context [1] for multithreading while dhcp is not there yet. Attaching simple patch to fix this particular issue but we'll see more until bz#1457871 is implemented.

Yes, that is bug I brought in by update of Bind libraries. I think it is missing commit https://source.isc.org/cgi-bin/gitweb.cgi?p=bind9.git;a=commit;h=fbfaa3e731ec73b6ae35de36725e0f870759f8a8, which is not included in rebased version. I am sorry for that regression.
