Hello.We are running pdns-4.5.1-1pdns.el8.x86_64 with MariaDB-server-10.4.21 as backend. I am seeing regular messages in our pdns 4.5.2 regarding deadlocks in MySQL.
Exception: GSQLBackend unable to nullify ordername and update auth for ovpn.spotsystem.net for domain_id 17651: Could not execute mysql statement: update records set ordername=NULL,auth=? where domain_id=? and name=? and disabled=0: Deadlock found when trying to get lock; try restarting transaction
I have found the following bug report on Github: https://github.com/PowerDNS/pdns/issues/8663 In the thread above is mentioned that setting|"default-api-rectify = no" resolves the deadlock if I did understand correctly.
What does 'api-rectify' do? And is it save to disable? Thanks, Thomas |
