Kontact restart method

I find that on more occasions than I'd like the server connection fails.
Often failure occurs when using the global search function.

It is yet to restart by via the gui supplied button.

I then check using akonadictl status and fond thet the server is not working

Then I attempt to either start or restart via akonadictl

:~$ akonadictl start
:~$ Connecting to deprecated signal 
QDBusConnectionInterface::serviceOwnerChanged(QString,QString,QString)
org.kde.pim.akonadiserver: Starting up the Akonadi Server...
org.kde.pim.akonadiserver: Failed to connect to database!
org.kde.pim.akonadiserver: Database error: "Can't connect to local MySQL server through 
socket '/run/user/1000/akonadi/mysql.socket' (2) QMYSQL: Unable to connect"
org.kde.pim.akonadiserver: Failed to remove runtime connection config file
org.kde.pim.akonadiserver: Shutting down AkonadiServer...
org.kde.pim.akonadicontrol: Application '/usr/bin/akonadiserver' exited normally...

This also fails and my action to date is to reboot the machine

Does an appropriate method exist to restore normal function without rebooting the entire 
machine?

Thanks
