Javascript 插座io和x2B；节点+；json实例崩溃

我的socket.io实例使用长轮询传输。当有超过400个并发连接时，为什么我的服务器会崩溃

该服务器有32GB的RAM和一个Xeon处理器

我已将用户列表存储在JSON文件中，并在将数据广播到客户端之前读取JSON文件

var fs = require("fs");
const fse = require("fs-extra");
var cors = require("cors");
const winston = require("winston");


//SSL certificate files
var options = {
    key: fs.readFileSync("./xxx.key"),
    cert: fs.readFileSync("./xxx.crt"),
    ca: fs.readFileSync("./xxx.ca-bundle")
};

//express framework intialize and listening on port 443
var express = require("express"),
    app = express(),
    //
    server = require("https").createServer(options, app),

    iohttps = require("socket.io")(server, {
        pingInterval: 30000,
        pingTimeout: 10000
    }).listen(server),
    server.listen(3000, "0.0.0.0");

var report_nsp = iohttps.of("/report");
app.use(cors())

report_nsp.on("connection", function(socket) {
    socket.on("new userlive", function(data) 
        socket.join(data.eventId);
        socket.uid = data.uid;
        socket.random_id = data;
        socket.userType = data.userType;
        socket.addRoom = data.eventId;

        if (!fs.existsSync(data.eventId)) {
            fs.mkdirSync(data.eventId);
            var Obj = {};
            Obj[socket.uid] = socket.random_id;

我的服务器如何处理至少1000个连接？

你能提供一些错误日志吗？尝试增加内存限制

节点--max old space size=8192 index.js#增加到8gb

@Andrew如果没有错误日志，我将尝试复制错误并存储它。我已经设置了--max old space size=8192
