Akonadi using 100% CPU resources

[piorunz <piorunz@gmx.com>]

Hi all,

I noticed that akonadi services are using 100% of 16-core CPU resources
on my machine. I don't even use Kmail, I use Thunderbird. I'm not even
sure what akonadi is for. I have following packages installed:

$ dpkg -l | grep akonadi | awk {'print $2'}
akonadi-backend-mysql
akonadi-contacts-data
akonadi-mime-data
akonadi-server
kmailtransport-akonadi:amd64
libkf5akonadi-data
libkf5akonadiagentbase5:amd64
libkf5akonadicalendar-data
libkf5akonadicalendar5abi1:amd64
libkf5akonadicontact5:amd64
libkf5akonadicore5abi2:amd64
libkf5akonadimime5:amd64
libkf5akonadinotes5:amd64
libkf5akonadiprivate5abi2:amd64
libkf5akonadisearch-bin
libkf5akonadisearch-data
libkf5akonadisearch-plugins:amd64
libkf5akonadisearchcore5:amd64
libkf5akonadisearchdebug5:amd64
libkf5akonadisearchpim5:amd64
libkf5akonadisearchxapian5:amd64
libkf5akonadiwidgets5abi1:amd64
libkf5mailimporterakonadi5:amd64
libkf5mailtransportakonadi5:amd64
libkf5pimcommonakonadi5abi1:amd64

System is Debian Testing.

How can I get rid of that akonadi, or disable it?

I can't uninstall akonadi-server, because it wants to uninstall with it:
akonadi-server* kaddressbook* kde-standard* kdepim-runtime* kmail*
knotes* korganizer* task-kde-desktop*

And dozens of libraries.

Any help appreciated.
