多亏了大家的帮助和建议在安装了Apache Server+Phusion Passenger+Capistrano，并为生产部署良好地配置了所有环境之后，一切似乎都运行良好。 （实际上，只有生产环境的webrick服务器是个坏主意……即使是测试版也是如此）
感谢所有帮助我们并回答我们问题的人。我的类似问题是因为我试图捕获404错误，但我有一个映射错误的图像，并且在锁定我的项目之前，一直处于错误页面。然后我也遇到了这个问题：
ActiveRecord::ConnectionTimeoutError (could not obtain a database connection within 5.000 seconds (waited 5.000 seconds))
解决方案是修复映射和任何其他类似的重复错误。作为从谷歌发现此错误的人的后续措施。如果使用Deviate，当Deviate无法正确初始化时，将发生此错误。如果您查看日志，您可能会发现在引导时发生另一个错误，这会阻止Desive初始化
在我的例子中，根本问题是我有挂起的迁移。只是想知道您正在生产服务器上使用webrick。无论如何，我想看看下面的文件：/home/dev/myProject/app/views/shared/_top_menu.html.erb:23，这样我就可以帮你了，我猜，_top_menu.html.erb第23行的代码如下：好的，这对我没有帮助。需要更多的产出。比如，你可以将设计相关的所有活动分享到GIST中。问题似乎出在你的设计配置上。缺少一些方法。我在日志中添加了第一个错误之前发生的另一个错误。我安装了puma服务器，并增加了连接池。但仍然是错误。。。我更新这篇帖子是为了向你展示我所做的一切，Weebrick会对你做的，我很幸运使用了
thinrails c用户发现了这个问题。
