Системный монитор, отслеживающий частоту сбора мусора сервера приложений
Системный монитор частоты сбора мусора отслеживает частоту, с которой выполняются операции сборки мусора в виртуальной машине Java, связанной с сервером приложений.
Неработоспособное состояние означает, что сборщик мусора превысил отслеживаемое пороговое значение, заданное для сервера приложений.
Запуск сервера приложений с конфигурацией, задающей больший объем памяти.
Перемещение некоторых развернутых приложений на другой сервер приложений.
