Question

这个经典集群示例：

var cluster = require('cluster');
var http = require('http');
var numCPUs = require('os').cpus().length;

if (cluster.isMaster) {
  // Fork workers.
  for (var i = 0; i < numCPUs; i++) {
    cluster.fork();
  }

  cluster.on('exit', function(worker, code, signal) {
    console.log('worker ' + worker.process.pid + ' died');
  });
} else {
  // Workers can share any TCP connection
  // In this case its a HTTP server

  // Worker code omitted
}

使用windows azure PowerShell和一个简单的节点进程在我的Windows机器上顺利运行，但是当我将它部署到azure模拟器或真正的辅助角色机器时，我收到以下错误：

spawn EBADF
    at errnoException (child_process.js:837:11)
    at ChildProcess.spawn (child_process.js:789:11)
    at exports.spawn (child_process.js:614:9)
    at exports.fork (child_process.js:443:10)
    at new Worker (cluster.js:288:20)

    at Object.Module._extensions..js (module.js:467:10)
    at Module.load (module.js:356:32)

任何人都知道为什么会发生这种情况或我如何调试此问题？

谢谢....

更新：此问题似乎只发生在节点引擎＆gt; = 0.8.0

相信这是在节点0.8.7中修复的

node.js中的群集在azure仿真器或azure vm中与EBADF失败
