MySQL failing , not connecting to database and "Connection for controluser as defined in your configuration failed" in phpmyadmin

December 2, 2014 2.1k views

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...

Im running Ubuntu 14.04

Thank you!

OOM is killing it because you're out of memory.

  • Thanks, I've come to realise this is specific to one website only (a Wordpress one), so I guess its not a server issue I should be looking at in terms of resolving this, but the website itself.
