Since my last update of Arch Linux, there’s one running mysqld process consuming one CPU core silently. I downgraded mariadb from 11.0.2 to 10.11.4, deleted $HOME/.local/share/akonadi and recreated the akonadi database, all these to no avail.
Running :
Operating System: Arch Linux
KDE Plasma Version: 5.27.6
KDE Frameworks Version: 5.108.0
Qt Version: 5.15.10
Kernel Version: 6.4.6-arch1-1 (64-bit)
Can someone else confirm this ? Any idea for a resolution ?
[nls@h2 ~]$ sudo mariadb -v
[sudo] password for nls:

The problem occurs on 2 machines. In the picture below, we see that one CPU core is near 100% usage in the ‘wait’ column, while the global ‘%CPU’ column reports 0. If the mysqld process receives a STOP signal, the red underlined usage drops down to 0%, and blows up to 100% again when the mysqld process receives a CONT signal.
I have just looked at your links, they seem to mean that the problem is not directly related to KDE. So I’ll wait for the next significant upgrades hoping it might be solved. (I should have visited your links first, sorry.)
