ECONNRESET：NODE JS

Question

我正在使用node.js代码将数据插入通过Excel文件发送的MySQL表中。我必须将此代码保持24小时运行，但是每隔15分钟我会收到ECONNRESET错误。正如您在代码中看到的那样，我尝试使用ws，但是问题仍然存在。

我也尝试过https://github.com/ionic-team/ionic-cli/issues/2921，但是每15分钟我都遇到同样的错误，但没有帮助。 我的代码有任何错误，请告诉我。

var express = require('express');
var server = express();
var bodyParser = require('body-parser');
var multer = require('multer'); 
var XLSX = require('xlsx');
var con = require('./dbconfig');
var WebSocket = require('ws')
const ws = new WebSocket("ws://localhost:3030");
ws.on('error', Error);
server.use(bodyParser.json());
//app.timeout = 0;
const http = require("http");
const originalOnSocket = http.ClientRequest.prototype.onSocket;
require("http").ClientRequest.prototype.onSocket = function(socket) {
const that = this;
socket.setTimeout(this.timeout ? this.timeout : 120000);
socket.on('timeout', function() {
    that.abort();
});
originalOnSocket.call(this, socket);
};
var servernew = http.createServer(server);
var storage = multer.diskStorage({ //multers disk storage settings
destination: (req, file, cb) => {
    cb(null, './uploads/')
},
filename: (req, file, cb) => {
    var datetimestamp = Date.now();
    cb(null, file.fieldname + '-' + datetimestamp + '.' + 
 file.originalname.split('.')[file.originalname.split('.').length - 1])
 }
  });

 var upload = multer({ //multer settings
 storage: storage,
 fileFilter: (req, file, callback) => { //file filter
    if (['xls', 'xlsx'].indexOf(file.originalname.split('.') 
 [file.originalname.split('.').length - 1]) === -1) {
        return callback(new Error('Wrong extension type'));
    }
    callback(null, true);
   }
   }).single('file');

    server.get('/', (req, res) => {
   //jdhs
    var workbook = XLSX.readFile(__dirname + '/uploads/demo.xlsx');
    var sheet_name_list = workbook.SheetNames;

     var xlData = 
    XLSX.utils.sheet_to_json(workbook.Sheets[sheet_name_list[0]]);
     console.log();
    let valueArrayj = jsonArrayToValueArrayj(xlData);
    con.query('INSERT ignore INTO demot Values ?', [valueArrayj], (err, 
    result) => {
        if (err) {
            res.json({ error_code: 0, err_desc: err, data: xlData });
            throw err;
        }
        else {
            console.log(result);
            res.json({ error_code: 1, err_desc: "Data Inserted 
   successfully", data: xlData });

        }
    });
    console.log(xlData);
 });

 ws.on('connection', (ws) => {

  ws.on('error', handleError);

   });
 //server.timeout = 0;
 server.listen('3030', () => {
 console.log('running on 3030...');
  });
