If this error occurs briefly during an update procedure (e.g. on an update from 12.5.30 to Onyx or on an upgrade of MySQL libraries) but after update completes it disappears again, do not worry about it. When libraries that affect MySQL are updated, MySQL becomes unavailable for a very short time, then restarts. During that time period Zend Engine cannot reach the database and throws this error.

However, if this error occurs constanly, e.g. you cannot login to Plesk, cannot open the login page etc., then the MySQL daemon is not running and must be restarted.
