Hello,

since a few days akonadi produces high CPU and disk load after start up. As long as akonadi is running, the CPU (four cores) have 100%. Only "akonadictl stop" helps.

Following processes increase the cpu (Also this agents are listet in the akonadiconsole as 'Offline, Idle'):

i'm on 4.8.13-1-ARCH and use akonadi 16.12.0-1

the informations and bugreports i found are very old. have anyone a idea what i can do to fix this?

You may want to try deleting the akonadi files. That's what I did when I realised what was occurring. The solution is found in this bug report comment here:

https://bugs.kde.org/show_bug.cgi?id=373443#c4

thank you very much... it sounds promising.
i will try that and report later.
