Question

Переодически на сервере отлетает база — любой новый коннект фейлиться

со словами database is shutting down, при этом открытые коннекты спокойно себе работают. Сопровождается вот таким трейсом. База запущена в докере, данные примонтированы в домашней папке, помогает перезапуск контейнера (создан с флагом —rm). Сталкивался ли кто-нибудь с такой проблемой?
