我制作了一个在线多人游戏，后端是 nodejs，有时当人们测试它时，他们会发送大量子弹或使用脚本创建大量玩家，我会收到错误。我对此有限制，因此游戏中只能有 500 个子弹和 20 个玩家，他们最终都会消失，但即使它不让人们创建太多子弹/玩家，当他们尝试时，我也会收到此错误：

zlib.js:499
      var newReq = self._handle.write(flushFlag,
                                ^

TypeError: Cannot read property 'write' of null
    at Zlib.callback (zlib.js:499:33)

我正在使用带有 express 的 socket.io。我的代码中与 zlib 无关，这些是我正在使用的唯一 npm 依赖项。

我正在使用的代码的一个 非常 精简版本（理想情况下不应以任何形式共享）：

//Dependencies
var express = require("express");
var app = express();
var server = require('http').Server(app);
var io = require('socket.io')(server);
var fs = require('fs');

/* a bunch of vars + config */

//Express
server.listen(7654);

//Some functions

//Socket.io Listeners
io.on('connection', function(socket) {

  //Declare Player
  socket.on("declare player", function (data) {
    if (Object.keys(players).length > maxPlayers) return; //Make sure no more than 20 players
    //If statements to check valid data was sent
    var playerdata = {
      //Player Data
    };

    //Referral code stuff

    //Secret Names
    switch (playerdata.name) {
      //Secret player codes for powerups
    }

    playerSecrets[data.id] = data.secret;
    players[data.id] = playerdata;
  });

  //Player Action
  socket.on("player action", function (data) {
    /* Player controls input, mostly redacted */
    switch (data.action.command) {
      case "shoot": //Shoot Bullet
        players[data.id].score--;
        if (bullets.length > maxBullets) return; //Maximum Bullets in Arena (500)
        bullets.push({/*bullet data*/});
        break;
    }
  });

});

//Kill Player
function kill(playerid) {
  delete players[playerid];
  delete playerSecrets[playerid];
}

//Generate stars

//Game loop
setInterval(function () {
  //Emit gamedata to clients
  io.emit("gamedata", {
    players: players,
    stars: stars,
    bullets: bullets,
    referrals: referralData
  });

  //For each player
  for (var i = 0; i < Object.keys(players).length; i++) {
    //Redacted
  }

  //For each bullet
  for (var i = 0; i < bullets.length; i++) {
    //Redacted
  }
}, 1000 / tickSpeed);

我想知道它是否与添加到 JSON/Arrays 的内容有关，因为当创建玩家/射出子弹时会发生这种情况，并且发送垃圾邮件会导致这种情况发生。请参阅 socket.on("player action" 和 socket.on("declare player" 。
