Idea跑Junit报错Native memory allocation (malloc) failed to allocate

这些时用idea跑junit时老是报错内存不足，具体报错信息如下：

#
# There is insufficient memory for the Java Runtime Environment to continue.
# Native memory allocation (malloc) failed to allocate 1745136 bytes for Chunk::new
# 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=
# This output file may be truncated or incomplete.
#
#  Out of Memory Error (allocation.cpp:390), pid=19388, tid=0x0000000000005668

这个错误困扰了我一两个星期，一开始在网上找到了类似的问题，答案都是说电脑内存不够，加内存解决。但是我电脑虽然是8G内存，但是经常占用率才65%左右时，用idea跑junit就会报这个错，这时内存也才占用70%左右，看了下可用内存还有2G左右，按理说不可能不够呀。然后也调整过Idea本身占用内存的大小，调整过JVM的内存大小，结果都不管用。

没办法，只好仔细研究上面这一大段具体的报错信息，在这里面看有没有什么有用信息了。首先，这个里面说的

In 32 bit mode, the process size limit was hit

这句话可以无视了，因为我电脑是64位系统，java也是64位的，所以根本不可能因为32位的进程限制导致报错，这句一开始误导我很久。然后它里面说可能的解决方法，除了减少系统里内存加载外，有一条是减少java堆大小，也就是xms和xmx的值，这点我是没有想通的，一般来说都是增大这两个值，好吧，既然它里面说减小，那就试试呗。结果当然是不出所料的没用。还有一条看似可能会有效的是

Set larger code cache with -XX:ReservedCodeCacheSize=

这个在启动工程时vm参数里可以设置，但是设置了这个值后启动直接报错无法加载vm。无语。好吧，回归到报错的第一句，

The system is out of physical RAM or swap space

系统可能超出物理内存或交换空间，首先物理内存肯定没有超出，那么肯定就是交换空间超出了。什么是交换空间呢？交换空间，在Windows系统中是指虚拟内存。调整交换空间大小即设置虚拟内存大小。这样就清晰了，就是电脑的虚拟内存设的不够，于是点开我的电脑->属性->高级系统设置->高级->设置->高级里，看到虚拟内存设的大小才1G。这显然不够呀，把它调到10G后，问题完美解决！

现在内存就算占到75%时用idea跑junit也可以正常执行了！看来windows系统并不是当物理内存不够时才会用虚拟内存，这一点我一直想错了，我以为既然物理内存还够用，怎么可能会用虚拟内存。
