当我导航到相关页面时,它加载正常.它似乎对大多数人来说很好,并且只是间歇地(很少)像这样崩溃.我注意到,只要它发生,用户代理就是机器人;最新的是Mozilla / 5.0(兼容; Baiduspider / 2.0; http://www.baidu.com/search/spider.html).但是我担心它有一天会发生在人类身上,所以我想知道是否有人知道我能做些什么呢？

更新

今天就出现了,用户已登录(幸运的是,该用户是我……虽然无法复制它).

再次,任何见解都会非常受欢迎！

我在Heroku上主持这个,并按照https://blog.heroku.com/archives/2013/2/27/unicorn_rails的说明使用Unicorn

解决方法

回答这个问题：

I’m really really keen to get this fixed,but I really don’t have any
idea where to start :/

你可以开始挽救这个错误,记录它,发送一封电子邮件给你,因为它只发生了几次,重试(使用“重试”命令).在此之后,您可能希望检查此IP执行的最后操作,并查看它是否相关.日志还记录会话变量.

也许你在高服务器使用时遇到了超时 – 尝试使用一个工具,使用一个新的,甚至可以自己记录内存使用情况,CPU使用率和磁盘使用情况以及其他信息.

编辑：

由于它不仅仅是一个动作,您可以像这样获取ApplicationController上的每个错误：

class ApplicationController < ActionController::Base
  rescue_from MyException,:with => :handle_my_exception

  def handle_my_exception
     grab_data
     send_mail
     retry
  end
 end

我认为这是一个特定的动作,所以我不确定重试是否适用于此.但即使你不能重试,你仍然可以通过这种方式获得更多信息并通过电子邮件发送给自己.当然,您需要添加重试计数器逻辑,否则您将遇到麻烦.

再次编辑：

更好地思考,您可以使用基于请求参数的redirect_to来模拟从那里重试.在这个答案中,他解释了如何得到它.别忘了发送参数.

How do I get the current absolute URL in Ruby on Rails?
