Nodejs: redis客户端报错 Redis connection gone from end event

错误的stack trace:

Error: Error: Redis connection gone from end event.at RedisClient.flush_and_error (/server/node_modules/redis/index.js:142:13)at RedisClient.connection_gone (/server/node_modules/redis/index.js:475:10)at Socket.<anonymous> (/server/node_modules/redis/index.js:103:14)at emitNone (events.js:111:20)at Socket.emit (events.js:208:7)at endReadableNT (_stream_readable.js:1064:12)at _combinedTickCallback (internal/process/next_tick.js:139:11)at process._tickCallback (internal/process/next_tick.js:181:9)

这个错是在客户端正在执行命令时，由服务端主动断开连接造成的，redis客户端在接收到服务端发来的FIN包后触发socket.end事件，然后调用“self.connection_gone("end");在connection_gone函数里会重新尝试建立连接。

function RedisClient(stream, options) {...this.stream.on("end", function () {self.connection_gone("end");});...
}

在报错时点上，服务端会有对应日志，例如：
