12台机器的集群 5.3.2 java1.8.131 已经配置内存锁定31g。现在不定期的其中某台会出现大量gc的记录然后导致集群无法工作，当我手工停掉这台es进程后，其他所有节点也产生了这样gc记录，最后没办法只能所有节点一起重启。

请问有啥办法吗还是配置我需要注意什么

     看这个记录大概觉得是CMS 然后FULL GC太多，年轻带只有1.4G，意味着堆分配不合理。。
     
    那么最简单的办法就是直接切换到G1GC。

    从GC日志看，老年代一直回收不了。ElasticSearch默认使用CMS垃圾回收器，当老年代使用了75%时就开始FullGC了，貌似官方还是不推荐使用G1，因为G1有些bug未解决会导致ES索引数据失败。具体可参考a-heap-of-trouble
    楼上有回答  "新生代只有1.4GB"，说堆配置不合理。我看了下默认情况下，新生代最大就只有1.4GB。(MaxNewSize参数)
      先 ps aux | grep elastic 找到你的ES进程pid，然后 jmap -heap pid 查看ES进程当前的堆 使用情况 和 GC配置，比如我的：
    GC配置信息：
    Heap Configuration:
       MinHeapFreeRatio         = 40
       MaxHeapFreeRatio         = 70
       MaxHeapSize              = 34359738368 (32768.0MB)
       NewSize                  = 1570308096 (1497.5625MB)
       MaxNewSize               = 1570308096 (1497.5625MB)
       OldSize                  = 32789430272 (31270.4375MB)
       NewRatio                 = 2
       SurvivorRatio            = 8
       MetaspaceSize            = 21807104 (20.796875MB)
       CompressedClassSpaceSize = 1073741824 (1024.0MB)
       MaxMetaspaceSize         = 17592186044415 MB
       G1HeapRegionSize         = 0 (0.0MB)
     
    堆使用情况：
    Heap Usage:
    New Generation (Eden + 1 Survivor Space):
       capacity = 1413283840 (1347.8125MB)
       used     = 71170512 (67.87348937988281MB)
       free     = 1342113328 (1279.9390106201172MB)
       5.035825782880246% used
    Eden Space:
       capacity = 1256259584 (1198.0625MB)
       used     = 34256104 (32.669166564941406MB)
       free     = 1222003480 (1165.3933334350586MB)
       2.726833246591176% used
     
    确保配置是合理的。另外，貌似ES官方不推荐给一个ElasticSearch进程分配大内存，32GB肯定是不能超过的。不然会有性能问题(指针压缩)，参考：heap-size
    其实为了保险起见，配置的内存最好不超过26GB，配置的内存越大，FullGC耗时越长，虽然我自己配的就是32GB（尴尬了……）
    另外ES6.3.2自动生成的gc日志文件：gc.log里面其实是有JVM相关配置的，比如我的：
    Java HotSpot(TM) 64-Bit Server VM (25.161-b12) for linux-amd64 JRE (1.8.0_161-b12), built on Dec 19 2017 16:12:43 by "java_re" with gcc 4.3.0 20080428 (Red Hat 4.3.0-8)

ly -XX:+UseConcMarkSweepGC -XX:+UseFastUnorderedTimeStamps -XX:+UseGCLogFileRotation -XX:+UseParNewGC

     
    然后为什么老年代一直回收不了，是不是 执行了什么使ES 缓存 数据的操作？？？
     
    多台机器组成一个ES集群，如果其中有台机一直在FullGC，CMS FullGC 有个阶段是存在Stop The World的，导致ES进程无法响应其他节点的ping请求，于是master就认为这台机器挂了，机器挂了，就会进行自动分片迁移(index.unassigned.node_left.delayed_timeout)，如果这台FullGC的机器自己是master的话，就会触发master选举。这些都会使集群工作不正常。

    大集群 G1GC试试 可以一定就解决了
    segment 索引过多了。调整优化下。
