com.mysql.jdbc.exceptions.jdbc4.MySQLNonTransientConnectionException: Никакие операции не разрешены после закрытия соединения

Я создал приложение и развернул его локально ... и оно отлично работало. Я развернул его на удаленном сервере и начал получать исключение, указанное в теме письма. Это не из-за проблем с брандмауэром.

Я изменил свой hibernate.xml на подключение через мой IP-адрес, а не через localhost, и теперь у меня такие же тайм-ауты в моем локально развернутом приложении. Я получаю эту ошибку, если продолжаю работу приложения более одного дня.

Я сам не выполняю никаких операций после совершения транзакций или закрытия сессий. Я использую следующие свойства в hibernate.cfg.xml

<property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property>
        <property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
        <property name="hibernate.connection.url">jdbc:mysql://myremotehost:3306/akp</property>
        <property name="hibernate.connection.username">root</property>
        <property name="hibernate.connection.password">root</property>
        <property name="hibernate.show_sql">false</property>
        <property name="hibernate.current_session_context_class">thread</property>
        <property name="hibernate.query.factory_class">org.hibernate.hql.ast.ASTQueryTranslatorFactory</property>

Вызвано: com.mysql.jdbc.exceptions.jdbc4.MySQLNonTransientConnectionException: Никакие операции не разрешены после закрытия соединения. Соединение было неявно закрыто драйвером.

Есть ли у кого-нибудь идеи, что может вызвать такое поведение?

РЕДАКТИРОВАТЬ: Теперь я использую следующее в моем файле hibernate.cfg.xml. Это правильно?
