Could Not Reserve Enough Space For Object Heap

Could not reserve enough space for object heap

Run the JVM with -XX:MaxHeapSize=512m (or any big number as you need) (or -Xmx512m for short)

Make sure you're running 64 Bit Java. Otherwise, go to the link above and get the Windows 64-Bit Offline download. then run that. Immediately fixed it for me.

Intellij occasionally unable to reserve enough space for object heap

Ultimately I was able to resolve the issue by updating the proper JDK.
My project was picking up on an incorrect JDK and hence was running the 32 Bit as opposed to 64 bit JDK.

Simply added the correct JDK under File > Project Settings.

It seemed that my project never required that much memory before, but once the need had risen, it seems that a 64 bit became required.

Issue was with version mismatch of plugins installed in sonarqube. I deleted jars for all plugins except java. This solved the issue.
I figured it out from sonar.log
Thanks

Android Gradle Could not reserve enough space for object heap

For Android Studio 1.3 : (Method 1)

Step 1 : Open gradle.properties file in your Android Studio project.

Step 2 : Add this line at the end of the file

org.gradle.jvmargs=-XX\:MaxHeapSize\=256m -Xmx256m

Above methods seems to work but if in case it won't then do this (Method 2)

Step 1 : Start Android studio and close any open project (File > Close Project).

Step 2 : On Welcome window, Go to Configure > Settings.

Step 3 : Go to Build, Execution, Deployment > Compiler

Step 4 : Change Build process heap size (Mbytes) to 1024 and Additional build process to VM Options to -Xmx512m.

Step 5 : Close or Restart Android Studio.

Java: Could not reserve enough space for object heap error, despite enough memory

The JVM can't just pick any old memory anywhere for its object heap, it has to be contiguous; meaning a continuous, unfragmented block of free memory. While you theoretically might have enough raw memory free to launch a JVM with this heap size, if it's not contiguous then it's useless as far as the JVM is concerned.

Note that this is far, far more likely to happen with a 32 bit address space (if you're using a 32 bit OS or 32 bit JVM), but can of course still happen regardless.
