Сайт не закрывает подключения к базе! Исправить.

Дело в том что сайт очень тормозит, и очень часто падает с такой ошибкой от Mysql:

Warning: mysql_connect() [function.mysql-connect]: User mdova already has more than 'max_user_connections' active connections in /usr/home/site/public_html/classes/DataBase/Class.php on line 22

MySQL Error! Name: NoConnection.

MySQL answer: User tete already has more than 'max_user_connections' active connections.

Дело не в сервере, процессор и память абсолютно не загружены, ресурсов хватает. Проблема в том, что движок сайта не правильно работает с базой данных – не закрывает подключения к базе, вот посмотрите:

mysql> show processlist;
