Zookeeper:Unable to read additional data from client sessionid 0x0, likely client has closed socket

Zookeeper异常记录：Unable to read additional data from client sessionid 0x0, likely client has closed socket

故障现象：

Zookeeper.out一直不断的刷新上述日志。问题：1、时间久后，终将会引起磁盘告警。2、不便于查看zookeeper日志信息.

原因：

由于128.1.2.215服务器有将zookeeper的2181端口对外。但无客户端与zookeeper建立连接。所以Zookeeper.out一直刷日志。

解决办法：

将128.1.2.215服务器里把2181端口对外的配置给注释掉或删除掉。然后重启相关服务即可。
