如何解决UBUNTU Minecraft Paper Server Java 运行时环境内存不足
我有一个 Microsoft Azure VM 实例正在运行，我安装了 minecraft 纸服务器。今天我无法启动服务器，因为在通过 ssh-putty 运行服务器命令时出现了一些 java 错误。
服务器操作系统： Ubuntu 18.04.5 LTS
minecraft 服务器运行命令：
sudo java -xms29G -Xmx29G -jar paper-1.16.4-416.jar nogui
OR
java -Xmx29G -xms29G -XX:+AlwaysPretouch -XX:+disableExplicitGC -XX:+UseG1GC -XX:+UnlockExperimentalVMOptions -XX:MaxGCPauseMillis=45 -XX:TargetSurvivorRatio=90 -XX:G1NewSizePercent=50 -XX:G1MaxNewSizePercent=80 -XX:InitiatingHeapOccupancyPercent=10 -XX:G1MixedGCLiveThresholdPercent=50 -XX:+AggressiveOpts -jar paper-1.16.4-416.jar

解决方法
Native memory allocation (mmap) failed to map 31138512896 bytes - 大约 31,14G，远高于您的 29G 限制。
似乎我禁用了过量使用 并且系统上当前分配的内存量几乎达到了极限。您可以在崩溃日志的 /proc/meminfo 部分看到它：
CommitLimit: 15951192 kB
Committed_AS: 15837036 kB
解决方案是启用启发式过量使用处理：
sudo sysctl vm.overcommit_memory=0
或增加过量使用率：
sudo sysctl vm.overcommit_ratio=100
