Kibana：没有生活的联系

我有ES 1.5.2群集与Kibana 4.0.1。 这包括4个数据/主节点以及4个客户端节点。 当我尝试加载kibana有时需要更长的时间来加载，或者有时我需要重新启动kibana所指向的ES客户端节点。 当问题出现的时候，

Kibana页面中出现控制台错误

Failed to load resource: net::ERR_EMPTY_RESPONSE - http://xx.xx.xx.xx /elasticsearch/_nodes 

和ES日志中的错误

 [2016-01-15 07:01:52,629][DEBUG][http.netty] [xxxxxx] Caught exception while handling client http traffic, closing connection [id: 0x8301fd2b, /xx.xx.xx.xx:54237 :> /xx.xx.xx.xx:9200] 

所有的主人有以下configuration
