Yes, I agree that this was not a too clever approach…

OK, but after fully stopping the daemon via systemctl (which of course disconnects all clients) and re-starting it, the
cacheis empty, isn't it? So the client after re-connecting /should/ find the proper function? In my case the full
restartdid *not* help, but produced the same error again afterwards! I didn't reboot the whole box, though.
This led me to the assumption that the database was “somehow” damaged.
