node.js：集群主进程异常：通道关闭

Question

我的node.js集群能够启动2个工作进程，并且工作正常。 这是伪代码。 但是，如果我打开Windows任务管理器杀死一个node.js进程，我预计它会重新启动。但它抛出错误（错误：频道关闭）。

if (cluster.isMaster) { 

    for (var i = 0; i < numCPUs; i++) { 
    cluster.fork(); 
    } 

    cluster.on('death', function(worker) { 
    logger.fatal('worker ' + worker.pid + ' died. Restarting again ...'); 

    cluster.fork(); 


    }); 

} else { 
    // Worker processes have a express server. 
    ......... 
    ......... 
} 

错误：

貌似有点毛病socket.io-clusterhub。这是一种配置错误或错误？

Answer 1

该问题已在最新的clusterhub版本0.1.2中得到解决 socket.io-clusterhub在内部使用clusterhub，因此如果更新了socket.io-clusterhub，它应该可以工作。
