通过crs日志可以看出，在14:50:31开始出现节点之间通信失败报错，随后节点2发生了重启。
（3） 查看节点2系统日志

系统日志无异常报错。
三、故障原因分析
根据日志信息可以看到，是由于节点之间心跳通信异常，导致节点2发生了重启，根据日志中的关键信息：
2024-10-05 14:50:45.484:
[cssd(10595)]CRS-1607:Node nxybj2 is being evicted in cluster incarnation 587229053; details at (:CSSNM00007:) in /u01/app/11.2.0/grid/log/nxybj1/cssd/ocssd.log.
2024-10-05 14:50:47.994:
[cssd(10595)]CRS-1625:Node nxybj2, number 2, was manually shut down
在mos上查询该报错，通过查询到的结果分析，该报错为bug：
受影响版本为：11.2.0.3，当前生成环境版本为：11.2.0.4，由此可以确定本次节点2重启是bug导致。
进一步查询，该bug在如下版本中进行了修复：
根据查询结果，要想修复此bug，就需要打对应版本的补丁。
