&引用；Java HotSpot（TM）64位服务器VM警告：无法保留共享内存。（errno=12）“；

我正在使用putty连接VM。在那里我安装了java8和tomcat8。当尝试使用tomcat作为远程服务器运行应用程序时，出现404错误

---

所以我重新启动了tomcat。在停止服务器时，我遇到此错误。有人知道这个问题的解决方案吗？

无法保留共享内存当JVM无法从共享内存为Java堆分配巨大页面时，可能会出现一条消息。只有当启用了

-XX:+UseLargePages

时，才会发生这种情况

errno=12表示“内存不足”

解释来自：

按照上面的说明操作，或者只删除

-XX:+UseLargePages

JVM选项

// Possible reasons for shmget failure:
// 1. shmmax is too small for Java heap.
//    > check shmmax value: cat /proc/sys/kernel/shmmax
//    > increase shmmax value: echo "0xffffffff" > /proc/sys/kernel/shmmax
// 2. not enough large page memory.
//    > check available large pages: cat /proc/meminfo
//    > increase amount of large pages:
//          echo new_value > /proc/sys/vm/nr_hugepages
//      Note 1: different Linux may use different name for this property,
//            e.g. on Redhat AS-3 it is "hugetlb_pool".
//      Note 2: it's possible there's enough physical memory available but
//            they are so fragmented after a long run that they can't
//            coalesce into large pages. Try to reserve large pages when
//            the system is still "fresh".
