Question

使用nodejs和pm2时出现此错误：

connect [MongoError: getaddrinfo EMFILE localhost:27017]
0|app      |     at Pool.<anonymous> (/home/ride4youco/public_html/node_modules/mongodb-core/lib/topologies/server.js:336:35)

0|app      |     at Socket.g (events.js:292:16)
0|app      |     at emitOne (events.js:96:13)

当我使用带有express和socket.io的节点时也许有人知道是什么原因造成的？

这是app.js：

var express = require('express');
var app = express();
var server = require('http').createServer(app);
global.io = require('socket.io').listen(server);
var compression = require('compression');
var helmet = require('helmet');
var session = require('express-session');

var bodyParser = require('body-parser');
app.use(bodyParser.json()); // support json encoded bodies
app.use(bodyParser.urlencoded({ extended: true })); // support encoded bodies

app.use(express.static(__dirname + '/src/'));

app.use(helmet());
app.use(compression());

app.use('/rides', require('./routes/ridesServer'));
app.use('/user', require('./routes/userServer'));
app.use('/offers', require('./routes/offersServer'));
app.use('/notifications', require('./routes/notificationsServer'));

server.listen("8080", function() {
  console.log("Connected to db and listening on port 8080");
});

一整个月都工作得非常好，当尝试使用重定向301或者一些新的套接字功能时，这种情况就开始发生了。我说NEW，因为我已经使用套接字功能整整一个月，一切都很好..我也评论那些套接字线，这仍然无法正常工作..

我必须提到它会在5分钟后再次起作用，然后经过一段时间它将无法再次工作..

我也遇到了这个错误：

0|app      | Error: EMFILE: too many open files, open '/home/ride4youco/public_html/src/fonts/open-sans/opensanshebrew-regular-webfont.woff'

我在所有路由之前将此行添加到app.js：

var fs = require('graceful-fs');

事情又恢复了。希望它能保持这样。
