How should I set the memory for IntelliJ 14?

I just upgraded my IntelliJ to 14.0.3. But there's always an Out Of Memory dialog popped up to ask me to set the memory.

Following is my settings: enter image description here

I thought it's enough. But the dialog shows from time to time, and sometimes, it's not responding that I have to shutdown it.

How should I set this for IntelliJ 14? Any ideas?

Open Intellij IDE's vmoptions file

For Mac Users

Help | Edit Custom VM Options...

or

Library > Preferences > Idea<YourVersion> > idea.vmoptions

For Window (32bit) Users

C:\Program Files (x86)\JetBrains\IntelliJ IDEA <your_version>\bin\idea.exe.vmoptions

For Window (64bit) Users

C:\Program Files (x86)\JetBrains\IntelliJ IDEA <your_version>\bin\idea64.exe.vmoptions

and setup it's memory as you wish. Below is sample settings for 2GB

-Xms128m
-Xmx2048m
-XX:MaxPermSize=350m
-XX:ReservedCodeCacheSize=240m
-XX:+UseCodeCacheFlushing
-XX:+UseCompressedOops

Hopefully this help.

You can set IntelliJ IDEA's memory settings and your application's memory settings in the following places:

IDEA's vmoptions file:

Under Windows it could be either of the followings, depending on which installation (x86, x64) you use:

  • C:\Program Files (x86)\JetBrains\IntelliJ IDEA 2016.3.4\bin\idea.exe.vmoptions
  • C:\Program Files (x86)\JetBrains\IntelliJ IDEA 2016.3.4\bin\idea64.exe.vmoptions

VM Options in the Run/Debug Configuration:

It really depends on the nature of the error. One thing to try is using idea64.exe instead of idea.exe.

If this doesn't help, please contact JetBrains by filing an issue to https://youtrack.jetbrains.com/newissue and attach your log there (Help | Show log).

If you still see this popup frequently even with high memory allocated, try:

File > Invalidate Caches / Restart...
