Heap size is not the total memory limit, the value of -XX:PermSize is also added to this number, plus stack size for every thread, plus memory mapped files, plus internal JVM memory for the JIT compiler and other needs. All these factors make it easy to get close or exceed the 2GB value. Also, increase build process heap size: if you use IntelliJ IDEA 2020.3 or newer, set 'User-local build process heap size' to 2048. If you use IntelliJ IDEA 2020.2 or older, copy value from 'Shared build process VM options' to 'User-local build process VM options' and add -Xmx2G to it. These changes will greatly reduce compilation time.
Tips & TricksThe default VM options for IntelliJ IDEA may be not optimal when your project contains more than 10000 classes and developers often try to change the default options to minimize IntelliJ IDEA hangtime. But sometimes the changes make things even worse.
So, how to configure IntelliJ IDEA VM options optimally? That’s not so easy question to answer, since the configuration strongly depends on the project being developed.
However, it is a well-known fact that JetBrains “eats its own dog food” and uses IntelliJ IDEA for development of new IntelliJ IDEA versions. Therefore, we can recommend some settings that our developers use and explain the general memory policy.
1. -Xms = 32m (64m)
2. -Xmx = 256m
Please note that very big Xmx and Xms values are not so good. In this case, GarbageCollector has to work with a big part of memory at a time and causes considerable hang-ups. On the other hand, too small values can lead to the OutOfMemory exception. The specified values provide enough memory and at the same time the GarbageCollector works often but rather fast.
One more important thing is to pay attention to the memory indicator at the bottom-right corner of IntelliJ IDEA. If it shows that the memory in use is almost equal to the total memory available (let’s say 195m out of 220m), we recommend you to increase Xmx on 50m or so.3. -XX:MaxPermSize=92m
This is a default value, and in most cases you don’t need to change it. You may increase it only if you get “OutOfMemoryError” in “PermGen space”.4. -server
Some people find IntelliJ IDEA more responsive with this option. But it is not guaranteed.
5. We don’t recommend to use the following options at all, since they are not very stable: -XX:+UseParallelGC
-XX:+UseAdaptiveSizePolicy
-XX:-UseConcMarkSweepGC
How to Run your Pycharm IDE under 64bit JVM.?
What is the real issue.?
First you should to know all jetbrains IDE's are written in Java. The issue because of your pycharm needs more memory to process your projects and files at the backend Java requires memory. But its not able to acquire that much of memory. So its closed obtrubtly.
Everyone will say increase the JVM/Java max heap size in pycharm.properties file. Then restart the pycharm. But thats not a permanent solution.
Brian eno cards oblique strategies pdf merge. The real problem is pycharm internally uses 32bit jvm which comes with the installer package. The 32 bit JVM can allocate maximum 2GB of space only.
What is the solution for it.?
So the fix is you have to start your pycharm with 64bit JVM. Here we will see how to start with 64bit JVM. Three steps to fix that
- Set the 64bit SDK as environmental variable
- create properties for 64bit version
- start the ide from .bat file

Set 64Bit SDK:
Before setting environmental variable you have to find out which version of java you are using. To find out Open Command Prompt → Then run the below command
java -version
It should have the 'Java Hotspot(TM) 64-Bit Server' line in the output.If there is no Bit information then its 32bit java. Then proceed furthuryou have to download and install the 64bit JDK from http://java.com/
Then open Control Panel → Edit Environmental Variable for Your Account Can you download hulu on macdownzup.
In User variables set PYCHARM_SDK and path will be your 64 bit javaversion
Create properties file:
For 64bit you have to create separate properties file for that. Createfile named as pycharm64.exe.vmoptions in the root directory of IDE
To start:
IDE should start with the pycharm.bat file.
This fix will work for other IDE such as WebStrom, PhpStrom, IntelliJand RubyMine from jetbrains also.
Basically you have to create <product>64.exe.vmoptions file. Set the 64bit Java environmental variable for that IDE. Then start the <product>.bat file

Environmental Variable for Different product:
- IDEA_JDK for IntelliJ IDEA
- WEBIDE_JDK for PhpStorm and WebStorm
- PYCHARM_JDK for PyCharm
- RUBYMINE_SDK for RubyMine
Phpstorm Max Heap Size
To know about what environmental variable have to use, open<product>.bat file. Then you will get to know.
