sentinel 内存泄露导致内存耗尽swap交换频繁

经查看redis 配置了五个节点，后来下线两个redis,但是sentinel依然显示五个节点，但是两个节点显示下线，但是sentinel依然每隔一秒钟去探测下线的服务器，此问题是sentinel的bug参见官方文档，在3.0.2中已经修复

* [FIX] Resolved a memoryleak in the hiredis library causing a memory leak

       in Redis Sentinel when a monitored instance or another Sentinel is

       unavailable. Every reconnection attempt will leak a small amount of

       memory, but in the long run the process can reach a considerable size.
