今天Idea授权码到期了，想着先用eclipse撑两天。结果打开直接闪退了。
直接上日志
#
# There is insufficient memory for the Java Runtime Environment to continue.
# Native memory allocation (malloc) failed to allocate 1391216 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=

很是奇怪， -Xmx设置的是768m，系统还有6G左右的空闲内存。应该不会存在内存不足的问题。根据日志提示的“Possible solutions”都没能解决问题。知道看到最后SYSTEM这段信息提示了swap交换分区只有大约8M了，初步判断是这里的问题。
Windows操作系统的swap就是虚拟内存，于是我抱着试试的心态去调整下虚拟内存。
我的是win11c操作系统，操作步骤如下：
1、进入“设置”，选择“系统”分类，再选型“系统信息”。
2、点击“高级系统设置”。
3、在弹出的界面选择“高级”选项，点击性能分组的“设置”。
