node 版本是多少？切换到 6.x 试试？

[liujingdong]

我用的是node版本是10.4.1,谢谢

[haoshengqian]

老铁，这个问题有头绪嘛，遇到同样的问题，跑一段时间就报错ERR_IPC_CHANNEL_CLOSED

[loskael]

@caihuiji 来改bug了

看了一下代码，ERR_IPC_CHANNEL_CLOSED 是因为 realTotalWorker 有异常没有处理，导致 cluster.fork 的 worker 退出了，这种情况为了保证健壮性，有两个解决方案：

1、在代码 https://github.com/BetterJS/badjs-storage/blob/591e1d142607407eb37a7c88665c35d605ca96b6/service/realTotalMaster.js#L22 处新增 disconnect/error/exit(三选一即可)的事件监听，在 worker 退出时，重新 fork 一个新的

2、在代码 https://github.com/BetterJS/badjs-storage/blob/591e1d142607407eb37a7c88665c35d605ca96b6/service/realTotalWorker.js 新增一个 process unhandledRejection 和 uncaughtException 的异常处理，保证遇到未知的错误不会导致进程退出

[caihuiji]

估计node 10 ipc 有问题。 我得找时间看看 @haoshengqian 是跑起来多久会有问题哈

[haoshengqian]

默认设置下，跑一个小时就会报错ERR_IPC_CHANNEL_CLOSED，怀疑是不是某个一小时跑一次的任务导致的

realTotalMaster.js line:23 新增一段：
// 进程关闭事件 cluster.on('exit', (worker, code, signal) => { console.log('工作进程 %d 关闭 (%s). 重启中...', worker.process.pid, signal || code); cluster.fork(); });
