我尝试在 Google 云平台上为我的 Minecraft 服务器创建一个 VM 实例。但几个小时后它就不断崩溃。它说我没有足够的内存，但我认为我为 Minecraft 服务器分配了足够的内存？我不太擅长 IT，所以我请求你的帮助。
最后错误日志：
There is insufficient memory for the Java Runtime Environment to continue.
Native memory allocation (mmap) failed to map 12288 bytes for committing reserved memory.
Possible reasons:
The system is out of physical RAM or swap space
The process is running with CompressedOops enabled, and the Java Heap may be blocking the growth of the native heap
Possible solutions:
Reduce memory load on the system
Increase physical memory or swap space
Check if swap backing store is full
Decrease Java heap size (-Xmx/-Xms)
Decrease number of Java threads
Decrease Java thread stack sizes (-Xss)
Set larger code cache with -XX:ReservedCodeCacheSize=
JVM is running with Zero Based Compressed Oops mode in which the Java heap is
placed in the first 32GB address space. The Java Heap base address is the
maximum limit for the native heap growth. Please use -XX:HeapBaseMinAddress
to set the Java Heap base and to place the Java Heap above 32GB virtual address.

答案1
您的内存不足。您的服务器有 5972MB 可用内存，其中 5800M 分配给了 JVM 中的内存分配池。这意味着操作系统的其余部分以及 JVM 本身总共共享 172MB 内存，这太低了。
因此，问题不在于您为 Java 进程提供的内存量，问题在于您试图提供的内存量超出了您拥有的内存量。您应该增加 VM 实例的内存。
至于多少内存才够用：我对 minecraft 服务器一无所知，所以 5.8G 可能就足够了。对于系统的其余部分，很容易猜到。停止 minecraft 服务器，然后运行命令free。“Mem”行中的“Used”列将告诉您系统当前使用了多少内存。在此基础上添加大约 50M（空的 JVM 会占用 30-40 MB 的内存），这就是系统运行所需的最低限度。
但是，最好提供更多内存，因为 Linux 将使用多余的内存作为文件系统缓存，如果 Minecraft 进程经常使用文件系统，这可能会派上用场。
