node.js - node.js 中的集群在带有 EBADF 的 azure 模拟器或 azure vm 中失败

Question

这个经典的集群示例：

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 模拟器或真正的工作角色机器时，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 Cluster.cluster.fork (cluster.js:474:11)
    at Object.<anonymous> (X:\workspaces\tp\deploy\local_package.csx\roles\zealot\approot\server.js:8:13)
    at Module._compile (module.js:449:26)
    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这个问题？

谢谢....

更新：这个问题似乎只发生在节点引擎> = 0.8.0

UPDATE2：打开一个问题https://github.com/joyent/node/issues/3779

相信这在节点 0.8.7 中已修复
