mod_jk быстрое переключение при отказе Tomcat, медленное при отказе хост-сервера

У меня есть две виртуальные машины, на каждой из которых размещен сервер Signle Tomcat (с активным соединителем AJP). Я включил липкую сессию.

Когда я выключаю сервер Tomcat, который в данный момент активен, переключение происходит быстро;
Однако когда я выключаю виртуальную машину, к которой я подключен, отработка отказа занимает минимум 40 секунд, прежде чем перенаправить меня на сервер UP / tomcat или выдать ошибку 502 bad gateway.

Есть идеи, почему поведение в каждом случае разное?

К вашему сведению, снижение worker.node1.maintain не помогает.

Конфигурация моих рабочих ниже.
