我面临一个奇怪的错误，这是我的主要 .js 文件

var cluster = require('cluster'),
  express = require('express'),
  http = require('http');

if (cluster.isMaster) {
    var cpuCount = require('os').cpus().length;
    for (var i = 0; i < cpuCount; i += 1) {
      cluster.fork();
    }
} else {
  var app = express(),
  server = http.createServer(app),
  io = require('socket.io').listen(server);
  io.set('log level', 2);
  server.listen(3000);
}

cluster.on('exit', function (worker) {
    console.log('Worker ' + worker.id + ' died :(');
    cluster.fork();
});

这是我收到的错误消息..

Worker 1 died :(
Worker 2 died :(

cluster.js 第 500 行是

assert(cluster.isMaster);

即你是fork从另一个工人那里打电话（或者 Node 认为你是）。

如果将cluster.on('exit'侦听器移动到if (cluster.isWorker)块中不能解决问题，那么我认为您应该在 Github 上打开一个问题，因为我看不出为什么该事件会在任何工作人员中发出。

编辑：这确实是一个错误。

有同样的问题 -现在正在工作：

cluster.on('disconnect', function(worker) {
  if (this.isMaster) {
    console.log('worker ' + worker.process.pid + ' disconnected');
    cluster.fork();
  }
});

正如@OrangeDog 所引用的。
