У нас есть приложение с пружинной загрузкой (2.0.2), которое выполняет операции crud с использованием транспортного клиента с поиском elasti c (6.2.4) с включенным активатором работоспособности. У нас также есть система мониторинга, которая срабатывает на привод работоспособности каждые 3 минуты и оповещает, если сервис не работает. Это приложение мониторинга оповещает от 6 до 8 раз каждый день, сообщая, что с ElasticSearch произошло исключение тайм-аута. Оповещения вызываются случайным образом каждый день без какого-либо паттерна.
Я нашел эти ссылки, но они были бесполезны. link1 , link2 и link3
Кто-нибудь знает, почему это происходит?
Вот журналы приложения на момент проверки работоспособности
