Hi! I read quite some times that people do akonadictl restart to work around and fix up issues with Akonadi temporily. I recommend: Don´t. Do - akonadictl stop, - then check that the mysqlq process is really gone - if it doesn´t quit after a while send it a TERM signal (please only the friendly TERM which kill sends if you do not specify a signal) - only after you are sure that there is no mysqld is running to akonadictl start again I think I completely lost the mysql database of my private Akonadi setup due to this as I tried out the SizeThreshold=32768 thing I mentioned a post ago. MySQL maybe would have been able to rebuild the db, but after writing excessively for 150-300 MiB/s for minutes to go with an write amount of easily tens of times of the whole size of the database I gave up on it. Also see: Bug 340813 - sometimes two copies of mysqld are running with Akonadi https://bugs.kde.org/340813 If you also see that akonadictl does not terminate all database processes, please comment to: [Akonadi] [Bug 248287] 'akonadictl stop' takes very long + doesn't terminate all 'mysqld' processes Also if you dare to start akonadi with a mysqld process still running and have then two mysqld processes running, comment to 340813. But I recommend: Don´t. Unless you have an IMAP account and are willing to have Akonadi rebuild the database from scratch in case the database is corrupted due to this. I think MySQL is trying to prevent data loss even in that case. It seems to lock ibdata file at least. But I am not sure whether this protection is complete and failure proof. It seems to me that it is not. So my recommendation is: Better do not risk it :).
