No idea what is PMM ?
https://www.percona.com/software/database-tools/percona-monitoring-and-manag... I prefer v1, but in Percona's build of PMM v1 there are several bugs / missing features that are going to cause you problems with newer kernels and MariaDB 10.5+. I have patches to fix it, but my build of it is not yet publicly available. But v2 is still far better than no PMM.
Do you have a bug tracking this behavior, so that maybe I can follow it or apply work-around ?
I cannot say I have looked. I'm generally happy to leave testing to others until I have an overwhelming reason to upgrade to a version with a lot of changes. And 10.5 was a rather big feature release.
I’m not quite keen on downgrading (which I’ll do using the spare servers I have and a little replication in between), but if it turns out to provide a more reliable alternative I’m eager to do it then!
Replication from newer version to older version is also not officially supported. It usually works, though.
