一样的问题，minor gc的频率跟不上老年代增长的速度，最后三个fe节点全部查询排队超时卡死宕机，建议用prometheus+grafana监控fe的JVM，看看到底问题出在哪，顺便改下你的参数，年轻代等于老年代的1/3，并且不要用-XX:NewRatio=3这种，而是固定设置成-Xmn16G，打开CMS的并行重标记，不然minor gc那点时间这么多内存根本标记不完，然后调低CMS初始化时的内存占比，80%太靠后了，可能gc没完成服务就down了，可以改成60或者65，实测有效，我的集群调整完至今没有fe宕机 -- This is an automated message from the Apache Git Service.
