Ошибка соединения с базой данных

Здравствуйте!
Прошу помощи, на сервере постоянно стал отваливаться вордпресс.
Ошибка соединения с базой данных, происходит в основном ночью.
Оперативка у сервера 8 гигов, 8 ядер. Стоит панель isppanel
База данных MariaBD, таблицы InnoDB

Уже и память увеличивал, нагрузка маленькая. 20% от ресурсов в пик.
