Right, as expected.

It doesn't seem to be a problem with the database server (it often is that's 
why I asked).

Two instances is strange. The double slash should be ok (same here).
If I do ps wwwauxf |grep mysql I get

That's ok, it is running until explicitly stopped.

It seems to be a problem in Akonadi Server, unrelated to the database.

Well, the Akonadi service crashed and restarting it didn't work a couple of 
times so the control process gave up.

Unfortunately this means we have something totally new here.
Stop Akonadi like this

% akonadictl stop

then check if there are now Akonadi processes running (e.g.output of 'ps x' 
does not contain any "akonadi" strings).
Check (or kill) remaining mysql instances.
Remove ~/.config/akonadi and ~/.local/share/akonadi and 
~/.kde/share/config/akonadi*rc


Check again that Akonadi is not running.
Try starting it
% akonadictl start

then

% akonadictl status

Cheers,
Kevin
