Websocket Rails死锁问题

在导致死锁错误的Rails 4应用程序中出现问题（详情如下）。我使用'websocket-rails'宝石。Websocket Rails死锁问题

这似乎是发生在每2要求，从dispatcher = new WebSocketRails('localhost:3000/websocket');来（从我的应用程序的前端）

我见过的很少，除了王菲内旧的问题没有提及这个问题的回购在GitHub上：https://github.com/faye/faye/issues/190

错误：

添加

config.middleware.delete Rack::Lock

到application.rb应该有所帮助。

到目前为止好！我以为我曾经在某处读过我不需要这样做，因为我的应用程序是 - 一直是 - 一个Rails 4应用程序。有关这条线如何解决我的问题的快速解释？ – paulruescher 2014-10-20 08:47:52

那么，这里是一个非常小的讨论：https：//github.com/websocket-rails/websocket-rails/issues/119（顺便说一句，你也可以启用'config.threadsafe！'代替）。 – bodrovis 2014-10-20 08:52:29

我也写了一篇关于Faye的文章，也许会有一些有趣的事情给你：http://www.sitepoint.com/realtime-mini-chat-rails-faye/ – bodrovis 2014-10-20 08:52:57
