Question

我正在监视运行ElasticSearch 6.2.3的Docker

每天都死了，我无法弄清为什么...

我认为这是记忆，但是在哪里可以找到证明呢？

我在主机（Linux）上运行最高虚拟记忆= 53演出分辨率= 26.7 马上！那是...

docker docker inspect给我这个

  "Memory": 34225520640,

        "CpusetMems": "",

        "KernelMemory": 0,

        "MemoryReservation": 0,

        "MemorySwap": 34225520640,

        "MemorySwappiness": null,

                "Name": "memlock",

JVM参数是

我认为Docker容器内存不足并无声地死掉

我如何证明这一点？而我该怎么解决呢？

Docker中的ElasticSearch默默消失并重新启动，但是为什么？
