I confirm I'm having the same bug on akonadictl 6.5.1 (25.08.1). This bug is likely related to https://bugs.kde.org/show_bug.cgi?id=422410 and https://bugs.kde.org/show_bug.cgi?id=458872. The symptom I have is: after disconnecting from VPN, akonadi uses 100% CPU, floods the log, overheats my computer and makes me never want to use KOrganizer again. It's really unfortunate, and I understand no one likes working with this kind of code (otherwise it would probably have been solved since 2020), but I'm afraid that, in the current state, the code brings too much instability and issues to users. I almost lost my laptop due to this, mainly because otherwise my KDE is so stable that I never have overheating issues.
