Hello, We've had the same issue with Ansible 2.7 on Debian 10 with many servers. We've had no issue with this until recently (last few weeks/months).
If we apply the patch manually, it works again. https://github.com/ansible/ansible/pull/40092/files Maybe something has changed in the MariaDB output. -- Jérémy Lecour - Responsable technique Evolix - PGP: F2D3E9D713FFDD52 Evolix - Hébergement et Infogérance Open Source Marseille (37 rue Guibal, Pôle Média, 13003) / Paris / Montréal http://evolix.com | Twitter: @Evolix @EvolixNOC | http://blog.evolix.com
