Ошибки Heroku R14 сразу при перезапуске

#ruby-on-rails #heroku #memory-leaks

#ruby-on-rails #heroku #утечки памяти

Вопрос:

У меня есть heroku приложение, в котором произошла утечка памяти, которую я не могу найти. Как только я перезапускаю приложение, оно сразу же достигает 100% оперативной памяти и выплевывается R14 errors . Я пробовал отладку с oink и не вижу никаких конкретных процессов, которые потребляют много оперативной памяти. Я также просмотрел мониторинг New Relic без результатов. По всем направлениям процессы идут медленно, и это потому, что приложение выполняется на диске, потому что оперативная память заполнена.

Я также попытался увеличить количество динамиков для Heroku, но я не добился улучшения производительности, потому что каждый динамик также мгновенно заполнялся.

Я использую mongoid , но я не думаю, что это проблема с БД, потому что у меня нет никаких объектов, созданных при загрузке приложения (но я не смог заставить oink работать с mongoid , поэтому не уверен в этом).

Как мне отладить, в чем проблема, если она настолько низкого уровня? Дайте мне знать, если мне нужно включить что-нибудь еще, что имеет отношение к отладке!

Procfile:

web: bundle exec puma -w 3 -t 16:16 -p $PORT -e $RACK_ENV

—Обновление: количество экземпляров объекта—-

Выполнение приведенного ниже дает мне экземпляры strings и различные другие объекты. Я думаю, что количество strings слишком велико, но я не могу найти информацию о том, как погрузиться в то, что создает строки.

 ObjectSpace.each_object.with_object(Hash.new(0)){ |obj, h|
  h[obj.class]  = 1
}.select{
|k,v| puts "#{k} => #{v}" if k == String || k == Array || k == Hash}

String => 689832
Array => 78652
Hash => 3390

Комментарии:

1. Есть ли у вас что-нибудь, что может выполняться при инициализации Rails? Если вы получаете эти проблемы при немедленной загрузке приложения Rails, это может быть проблема в самой вашей настройке Rails?

2. Да, в принципе, так оно и было (с настройкой сервера).

Ответ №1:

После тонны отладки и пробования разных вещей я в конце концов обнаружил, что проблема была в конфигурации сервера. Мой Procfile раньше читал:

web: bundle exec puma -w 3 -t 16:16 -p $PORT -e $RACK_ENV

Который увеличил количество потоков до 16 с 3 рабочими. Я обновил его после прочтения этой статьи. Я собираюсь продолжить отладку, чтобы увидеть, что работает лучше всего, но это уже огромный прирост производительности.

web: bundle exec puma -t ${PUMA_MIN_THREADS:-8}:${PUMA_MAX_THREADS:-12} -w ${PUMA_WORKERS:-2} -p $PORT -e ${RACK_ENV:-development}
