Мы используем класс c Rails архитектуры
- AWS EC2 в качестве хоста веб-сервера
- AWS ElastiCache в качестве кэша
- Puma
- Sidekiq
Когда в нашем приложении произошли какие-то уведомления, наше веб-приложение отправит уведомление по электронной почте нашему клиенту через задание Sidekiq. Проблема в том, что наш инструмент мониторинга показывает, что с нашей работой по отправке электронной почты в производственной среде происходит множество ошибок Errno::EPIPE.
