One particular problem (causing huge memory and/or CPU time) I do remember 
(not from actual experience, but from reading bug reports) was caused by 
broken/corrupted agent_config_*_changes.dat files in the ~/.config/akonadi/ 
folder.
Deleting them helped (and should not cause data loss) apparently.

But that was years ago, should probably not occur nowadays...

Yeah, that's because folders are referred to by their (numerical) id in the 
Akonadi database.
"Fixing" that would probably cause other problems though AIUI.
