Развертывание Keycloak 4.5.0. Наконец, в среде Openshift, использование Mariadb (Galera) в качестве базы данных приводит к нескольким исключениям в журналах, причем все они связаны с взаимодействием между сервером Keycloak и базой данных.Доступ к серверу Galera (3 экземпляра) осуществляется через прокси-сервер Maxscale.Сервер Galera, Maxscale (развертывание из 3 модулей) и Keycloak (развертывание из 2 реплик) развернуты в Openshift на AWS (1master + 3 работника).
Надеюсь, вы, ребята, можете помочь с исправлением этих проблем.проблемы.
Ошибки выглядят следующим образом:

Я подозреваю, что ошибки происходят из-за конфигурации источника данных jdbc.Конфигурации mariadb, относящиеся к соединениям и тайм-аутам ожидания, приведены ниже:
max_connections=1000
wait_timeout=180
Вторая проблема, на которую я обратил внимание, заключалась в следующем: одна из модулей в развертываниях (мы развертываем 2 реплики Keycloak) иногда не запускаетсяправильно из-за следующего исключения, которое все еще связано с подключением к базе данных:

Кажется, модуль несколько раз перезапускается, но он запускается неправильно.Я удалил модуль, и он был автоматически воссоздан Openshift, и новый модуль запустился правильно.
Затем возникла третья проблема, с которой я столкнулся при попытке войти в развернутое приложение.При вводе неправильных учетных данных я получил страницу с ошибкой и заметил в журналах, что по-прежнему существует ошибка подключения к базе данных:
