Max Connections Limit Error

When you see error like this:

SafeMySQL: 1203 User some_db_username already has more than ‘max_user_connections’ active connections

then you reached your server limit for database simultaneous connections. You can rather ask your hosting to increase max_connections for MySQL or you can try to switch plugin to WP wrapper for DB operations. You can enable this if you add to your wp-config.php next line:

define('WP_USE_EXT_MYSQL', false);
define('FF_USE_WPDB', true);

and deactivating/activating plugin after.

Though WP wrapper is less performant but it requires at the same time less server resources which can help  if your server struggles to handle and update a lot of streams.
