Description
After upgrading part of our systems to 10.6.11 the MariaDB server uses much more CPU compared to 10.6.10.
We were upgrading to 10.6.11 for the fix to MDEV-29843, but started to roll back due to load issues with that version.
Server config is the same as on MDEV-29843;
~8 MariaDB instances per server, issue is worse on systems with a higher number of queries, where it's using 100% cpu, with notocable repsonsiveness of the system
