CLion Out of Memory Issues

Question

I ran a simple CLion project with only two directories which each contain a single file. However, I was getting this message “Out of Memory”. I increased the Xmx from 2GB to 4GB. I believe this is more than enough. How can I fix this problem?

This is the settings in the clion64.exe.vmoptions file:

   -Xss2m
   -Xms256m 

   -Xmx4000m

   -XX:MaxPermSize=350m

   -XX:ReservedCodeCacheSize=96m

   -XX:+UseConcMarkSweepGC

   -XX:SoftRefLRUPolicyMSPerMB=50

   -ea

   -Dsun.io.useCanonCaches=false

   -Djava.net.preferIPv4Stack=true
