Heroku R14錯誤＆Amazon S3＆RefineryCMS

Question

我目前正在使用在Heroku（免費版）上設置的RefineryCMS，該資源與Amazon S3帳戶集成在一起以存儲和提供圖像。

我繼續獲得超過Ruby（MRI）的R14內存配額。 這只發生在我有Rails代碼提供文件的頁面上（例如https://scape-cms.herokuapp.com/projects ）。 我在精煉CMS上直接插入圖像的其他頁面（例如https://scape-cms.herokuapp.com/contact-page ）也不錯。

這是我從Heroku獲得的重復錯誤日志：

我的源代碼可以在這里找到：github.com/lltheis/scape-cms。

我對從這里去哪里不知所措-從概念上講，我似乎應該能夠提供存儲在S3上的圖像，因為它們的大小為164KB到500KB-因此應該在限制范圍內。 但是我的進程達到了512MB的極限。

謝謝！

Answer 1

問題可能是多種的：

1. 蜻蜓可能會通過imagemagick消耗大量內存： http ： //astrails.com/blog/2014/7/28/dragonfly-imagemagick-and-memory-bloat

可以通過添加以下內容來解決：

# config/initializers/dragonfly.rb
Dragonfly.app.configure do
  plugin :imagemagick, identify_command: "identify -limit memory 0 -limit map 0"
end

2. 緩存策略可能有問題，您在生產中使用什么？
3. 當前在您的Heroku應用程序上使用的工作人員數量可能有問題： https ： //devcenter.heroku.com/articles/ruby-memory-use

我希望這會有所幫助，很難找到有關R14錯誤的問題。
