Node.js(带有socket.io和express)抛出“events.js：71 throw arguments [1]; //未处理的’错误’事件“

我正在使用socket.io运行express(通过Nginx代理)并且片刻之后(应用程序一段时间工作正常)控制台抛出这个：

events.js:71
        throw arguments[1]; // Unhandled 'error' event
                       ^
Error: socket hang up

    at Socket.emit (/home/xyz/chat/node_modules/socket.io/lib/socket.js:368:15)

有任何想法吗？

解决方法

如果你使用的是node.js版本0.8.20,那么包括我在内的许多人都会看到这个错误.

将node.js升级到版本0.8.21解决了这个问题.
