The sistem : Ubuntu 14.04 - Plesk 12

After upgrading to the latest Plesk and restarting the VPS , Mysql refuse to start.

"ERROR: PleskDBException: Unable to connect to database: mysql_connect(): No such file or directory (Error code: 2002) (Abstract.php:69)"

Thank you, we got the information from our system engineers, there was a problem
accessing the official Plesk repositories during the last restore which has
caused a failure of the last installation.

The problem is with latest MySQL update on Plesk 12.5.30.
They take it off from the repository list.
But when update from 12 directly to Plesk 12.5.30. the problem persist. After restart mysql failed to start.

After I use the command "killall mysqld" the mysql starts to working OK, until I restart again the server !

Any idea ?

Make sure that your VPS has enough allocated resources for correct Mysql and Plesk operation.
