Question

我在node.js中有一个简单的队列显示应用程序。它将用户显示在显示器上的队列中。应用运行正常。我们目前在许多服务器上运行它。问题是，在一些服务器上，一段时间后（永远列表显示一个示例运行15天）它停止响应并且netstat显示没有监听端口3000.

代码：

// Module dependindex.html
var express    = require('express'),
    mysql      = require('mys');

// Application initialization
var connection = mysql.createConnection({
      host     : 'mysql.host',
      user     : 'root',
      password : 'pw',
      database : 'db',

    });
var app = express();

app.use(express.urlencoded());

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

// Page configuration (html pages are tempulates)
app.get('/', function(req,res) {
  res.sendfile(__dirname + '/index.html');
});

// Application routes
// mysql calls/logic here
app.post('/', function(req, res){
  var query = "SELECT aa.id, aa.first_name, aa.last_name, aa.gwf, ac.counter_stage, aa.queue_call_by_flag, ac.counter_name FROM `agent_counters` ac LEFT JOIN `applicants` aa ON aa.id = ac.next_applicant WHERE ac.call_next = 1 AND ac.next_applicant is not null";
  connection.query(query, req.body, function(err, rows, fields) {
    if (err) throw err;
    var obj = {};
    var prop = "";
    var gwf_name = ""
    for (var i = 0; i < rows.length; i++) {
      var current_stage = "";
      switch (rows[i].counter_stage) {
        case "documentation":
          current_stage = "Documentation";
          break;
        case "biometrics":
          current_stage = "Biometrics";
          break;
        case "interview":
          current_stage = "Interview";
          break;
      }
      prop = "gwf" + i;
      if (rows[i].queue_call_by_flag == 'gwf') {
        gwf_name = rows[i].gwf;
      } else {
        gwf_name = rows[i].first_name + ' ' + rows[i].last_name;
      }
      obj[prop] = gwf_name + '|' + rows[i].counter_name + '|' + current_stage + '|' + rows[i].id;
    }
    res.send(JSON.stringify(obj));
  });
});

// Begin listening
app.listen(3000);
console.log("Express server listening on port %d in %s mode", '3000', app.settings.env);

我已将服务器设置为使用Forever模块Forever运行命令：

Forever start app.js

任何帮助都将不胜感激。
