Ruby on Rails网站在Nginx上运行502错误

我的Ruby on Rails网站正在抛出零星的502错误。 它运行在Nginx上，与Passenger一起安装，托pipe在运行Ubuntu 10.04的服务器上。 看来错误变得越来越稀疏，但是它们仍然造成了一个问题。

我猜测它与缓冲区大小有关，但我不确定。

我知道有同样问题的人还有其他一些问题，但是这似乎很奇特。

在此先感谢您的任何帮助或build议。 我可以给你任何你可能需要的规格或版本号。

• Nginx代理Node.js返回400在SSL下
• 带有Nginx的fastcgi-mono-server比xsp4慢得多
• mediawiki和wordpress MU与Nginx不同
• .htaccess到Nginx的具体脚本/文件夹？
• 带有proxy_cache的Nginx ssi在第一次请求后挂起
