Question

大家好我有一个用Express.js编写的应用程序，我使用socket.io向用户显示实时数据。

当有更多然后让网站上的10个用户突然节点服务器崩溃并且我收到此错误

path.js:309 var path = (i >= 0) ? arguments[i] : process.cwd();

即使我独自在网站上，我多次刷新页面，或者只是停留在网站上并点击页面我得到同样的错误，有谁知道如何解决这个问题？

编辑：这是整个错误

path.js:309
      var path = (i >= 0) ? arguments[i] : process.cwd();
                                                   ^

看起来这是一个“太多打开文件”错误，如果您的应用与文件系统中的大量文件进行交互，则可能会发生此错误。你没有说明你的平台是什么，我假设Linux，通过链接建议的修复是你的ulimit。

完整的引用修复：

EMFILE表示打开的文件太多。早午餐监视所有项目文件，它通常是一个非常大的数字。您可以使用命令ulimit -n <number>将最大打开文件数设置为更大的数字来修复此错误（10000应该足够了）。

Node.js，path.js在很多用户连接到应用程序后崩溃
