    根据以上日志信息推测：由于集群主节点192.168.72.31发生存储类型的等待事件，导致主节点192.168.72.31拒绝2个从节点192.168.72.32/33的TCP连接

2、根据步骤1中的提示，查看mongo服务在操作系统层次的日志，操作系统日志从2018-1-5 4:59:25秒就已经告警提示D盘已经满载

3、查看192.168.72.31存储情况，果然如操作系统日志提示，D盘只剩余58MB的可用空间

4、由以上信息可以断定：由于Mongo集群主节点192.168.72.31存储空间满，导致主节点192.168.72.31的Mongo进程无法完成写操作从而拒绝2个从节点的连接导致整个mongo集群服务中断。经沟通得知，地市技术对当前Mongo主节点192.168.72.31数据做了备份，没有注意到D盘存储情况。
事后，地市技术立即删除节点192.168.72.31的冗余数据备份释放D盘空间，由于调度程序处于僵死状态，地市技术决定重启整个mongo集群服务器192.168.72.31/32/33。

5、重启完成后，mongo集群恢复正常，主节点192.168.72.31的mongo控制台提示调度程序bmi被接受连接到mongo集群的admin库
