IntelliJ IDEA之内存不够提示os::commit_memory failed

发现问题

平时的开发都很够跑，但是一搞微服务就GG了，内存占用太严重，需要加大内存了！！！

解决方案：

找到idea安装目录，打开idea.exe.vmoptions文件，进行编辑，加大各项参数。例如我的是

D:\software\IntelliJ IDEA Community Edition\bin\idea.exe.vmoptions

-server
-Xms1024m
-Xmx2048m
-XX:ReservedCodeCacheSize=512m
-XX:+UseConcMarkSweepGC
-XX:SoftRefLRUPolicyMSPerMB=50
-ea
-Dsun.io.useCanonCaches=false
-Djava.net.preferIPv4Stack=true
-XX:+HeapDumpOnOutOfMemoryError
-XX:-OmitStackTraceInFastThrow
