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.


I have solved this problem by changing the build settings in Intellij. Please follow the below steps.

For SBT: 1. Go to File -> Settings -> Build, Execution Deployment -> sbt 2. Change the value of Maximum heap size, MB to your available memory. Ex. 512 (Previously this value was 1536, due to this I faced the problem)

For Maven: 1. Go to File -> Settings -> Build, Execution Deployment -> Maven -> Importing

  1. Change the value of VM options for importer to your available memory. Ex. -Xmx512m
