Java HotSpot(TM) 64 位服务器 VM 警告 : failed; error ='Not enough space' (errno=12)

Question

遇到以下错误 - 在安装和运行我自己的应用程序时。

Java HotSpot(TM) 64-Bit Server VM warning: INFO: os::commit_memory(0x000000008a660000, 1973026816, 0) failed; error='Not enough space' (errno=12)

KiB Mem :  3852964 total,   358468 free,  3011660 used,   482836 buff/cache

KiB Swap:        0 total,        0 free,        0 used.   515060 avail Mem 

空间分配如下我的系统正在消耗空间，详情如下

Java HotSpot(TM) 64-Bit Server VM warning :

There is insufficient memory for the Java Runtime Environment tocontinue.

Native memory allocation (malloc) failed to allocate xxxxx bytes forcommitting reserved memory.

Possible reasons:

• The system is out of physical RAM or swap space
• In 32 bit mode, the process size limit was hit

Possible solutions:

• Reduce memory load on the system
• Increase physical memory or swap space
• Check if swap backing store is full
• Use 64 bit Java on a 64 bit OS
• Decrease Java heap size (-Xmx/-Xms)
• Decrease number of Java threads
• Decrease Java thread stack sizes (-Xss)
• Set larger code cache with -XX:ReservedCodeCacheSize=

If you are on Java 8 or later, please also see this question: Java HotSpot(TM) 64-Bit Server VM warning: ignoring option MaxPermSize

当然Java HotSpot VM Options也会很有用。
