内存不足，无法运行Java运行时环境以继续
我有一个带有4 GB内存的Windows操作系统。我安装了VMWare，以使用2GB RAM设置Ubuntu虚拟机。在Ubuntu中，我打开Eclipse并开始编码，Eclipse开始一次又一次地关闭，我开始出现以下错误：内存不足，无法运行Java运行时环境以继续,java,linux,eclipse,out-of-memory,heap-memory,Java,Linux,Eclipse,Out Of Memory,Heap Memory,我有一个带有4 GB内存的Windows操作系统。我安装了VMWare，以使用2GB RAM设置Ubuntu虚拟机。在Ubuntu中，我打开Eclipse并开始编码，Eclipse开始一次又一次地关闭，我开始出现以下错误： There is insufficient memory for the Java Runtime Environment to continue.

There is insufficient memory for the Java Runtime Environment to continue. Native memory allocation (mmap) failed to map 28311552 bytes for committing 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=

可供eclipse使用的内存太少。最好是用更多的ram升级您的系统
除非您有充分的理由不直接在windows下使用eclipse而不使用virtual box。如果您必须使用Ubuntu，请考虑使用Ubuntu和java和Eclipse的32位版本，或者在Windows旁边安装Ubuntu，这样您就可以引导它进入并拥有所有的内存。p> Java虚拟机进程内存不足 你可以做的事情有几种可能性。在我看来，如果您想保持流程的当前限制，以下可能性是最有希望的：
- 减小Java堆大小（
/-Xmx
）：-Xms
在
中，可能有一行类似于eclipse.ini
的代码，您可以用-Xmx1024m
来代替。请尝试哪个最大堆空间仍然足以满足您的需要。确保-Xmx640m
不大于-Xms-Xmx - 如果且仅当您有64位系统时，您可以使用Eclipse 64位和而不是当前使用的Eclipse 32位和Java HotSpot 32位虚拟机。默认情况下，OpenJ9在内存消耗方面效率更高，还可以在这方面进行进一步调整
此处似乎给出了在64位操作系统上使用64位Java的可能性，因为64位Java虚拟机可以寻址更多内存，但是它的内存效率比等效的32位虚拟机低。你有没有尝试过错误给你的建议列表？@Shawn你能解释一下我们如何准确地执行那些将要解决的建议吗。参数以
