Question

我目前正在使用与Amazon S3帐户集成的Heroku（免费版）上设置的RefineryCMS来存储和提供图像。

我继续在Ruby（MRI）中获得超过R14内存配额。它只发生在我有Rails代码服务我的文件的页面上（例如https://scape-cms.herokuapp.com/projects）。我通过Refinery CMS（例如https://scape-cms.herokuapp.com/contact-page）直接插入图像的其他页面也没问题。

以下是我从Heroku获得的重复错误日志：

我的源代码可以在这里找到： github.com/lltheis/scape-cms。

我不知道从哪里开始 - 在概念上似乎我应该能够提供存储在我的S3上的图像，因为它们是164KB到500KB - 所以它们应该在极限之下。但在某些地方，我的流程达到了512MB的限制。

谢谢！

问题可能是多方面的：

使用imagemagick，Dragonfly可以消耗大量内存： http://astrails.com/blog/2014/7/28/dragonfly-imagemagick-and-memory-bloat

可以通过添加以下内容来解决：

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

这可能是缓存策略的问题，您在生产中使用了什么？
目前Heroku应用程序上使用的工作人员数量可能存在问题： https://devcenter.heroku.com/articles/ruby-memory-use

我希望这可以提供帮助，很难找到R14错误的问题。
