ruby-on-rails - Heroku 错误 R14(超出内存配额): How do I solve this?

标签 ruby-on-rails ruby-on-rails-3 memory heroku memory-management

我在 Heroku 上有一个 Rails 3.1 应用程序。我看到很多这样的错误:

Error R14 (Memory quota exceeded)

通常会显示前面的日志条目:

Process running mem=522M(102.1%)

这确实会有所不同，但不会相差太大，并且几乎可以在任何 URL 请求之后发生，因此据我所知，它与特定的 Controller 操作无关。

这是一个经典的日志条目 block :

我安装了 New Relic，但无法识别任何有用的东西。

如果需要，我们很乐意提供更多信息。我在 Heroku 上也有一个 Unresolved 支持请求，但到目前为止(标记为紧急 2 天)我还没有回复。

添加 web dynos 没有区别。

更新，我添加了 oink gem，这是一个示例结果

我不知道这能证明什么，只是我似乎没有像 Heroku 认为的那样使用那么多内存 内存使用:288876 vs Process running mem=537M(105.0%)

最佳答案

查找带有 'Model.all.each do |something|' 的代码并替换为 Model.find_each do |something|。这将通过将模型的 block 而不是一次全部加载到内存中来节省内存。

另外，寻找机会使用 in_groups_of 或 :limit 来减少一次保存在内存中的对象数量。

编辑:for_each -> find_each。
