From time to time something goes wrong with MySQL, I get the above error and no databases will connect.

The only way I can fix it is by running

"sudo shutdown -r now"

Has anyone any suggestions for fixing this issue, or getting the cause of it? I found this thread but no luck there...

Thank you!
