Ruby on rails Rails 4.0.0在现有路由中遇到定期路由错误异常（404）

ruby-on-rails ruby nginx

Ruby on rails Rails 4.0.0在现有路由中遇到定期路由错误异常（404）,ruby-on-rails,ruby,nginx,puma,Ruby On Rails,Ruby,Nginx,Puma,问题是，我们的站点定期为存在的路由呈现404 RoutingError异常；甚至根路径这个问题似乎在一天中最忙的时候突然出现。如果刷新页面，页面可能会正确呈现，也可能不会如果Puma被刷新，该问题将暂时缓解实际存在的路由的这些404异常的puma日志与实际不存在的路由的404异常的puma日志完全相同。下面是一个日志示例： ActionController::RoutingError (No route matches [GET] : "/app" actionpack (4.0.11

问题是，我们的站点定期为存在的路由呈现404 RoutingError异常；甚至根路径

这个问题似乎在一天中最忙的时候突然出现。如果刷新页面，页面可能会正确呈现，也可能不会

如果Puma被刷新，该问题将暂时缓解

实际存在的路由的这些404异常的puma日志与实际不存在的路由的404异常的puma日志完全相同。下面是一个日志示例：

此路由确实存在，但服务器仍在向请求提供404

我不知道发生了什么，所以我在下面介绍了服务器的配置

通过Capistrano部署Puma
