Hi Darren, Thank you, that's fixed it. I'm not sure why I didn't spot that blindingly obvious error message pointing me to the exact line in my logging configuration file! I've REM'd out that line (prefixed with '//') and the upgrade progressed successfully. Obviously something's changed in 9.19.12 and up.
For info the source of my logging file is this, and it's what I've been using for quite a few years now. But I don't actively review that specific log file so I haven't lost anything by removing that statement. https://kb.isc.org/docs/aa-01526 It was indeed this line that caused all the problems, REM'ing it out has fixed it: category delegation-only { auth_servers_log; default_debug; }; Thanks again for your help Darren, Richard. -----Original Message----- From: Darren Ankney <darren.ank...@gmail.com> Sent: Monday, July 10, 2023 9:07 PM To: Richard T.A.

It would be helpful to see the named configuration. You can get that with named-checkconf -px which will hide any keys and pull in any includes.
