Invalid maximum heap size?

Question

I am running an grails application for my project in IntelliJ and I have set the vm options to :

-Dserver.port=8080 -Xms3g -Xmx3g -XX:-UseGCOverheadLimit -Xverify:none

The logs are :

Running Grails application

Invalid maximum heap size: -Xmx4096M

The specified size exceeds the maximum representable size.

Error: Could not create the Java Virtual Machine.

Error: A fatal exception has occurred. Program will exit.

Error | Forked Grails VM exited with error

Please help me with that ?

How much RAM you have available? What operating system do you use? Which JDK have you installed? – Bendick

Answer 1

If your JVM is 32bit, then heap size should be lower than 4gb. Either you can install 64bit JVM, or set the maximum heapspace to 2GB with -Xmx2048M. I had similar problem and this worked for me, hope this helps you as well.

i have jdk installed amd-64 does it includes jvm ? – Garage

please run "java -version" in command line to see whether jvm 32 or 64. And yes jdk contains everything that is in the jre, because jdk is superset of jre – Target

I have ubuntu installed it is not showing whether jdk is 32 bit or 64 bit. Please help. – Garage

Please tell me what you see on the third line when you open your terminal and run the following command: java -version. you should be seeing OpenJDK 32 or 64 -Bit – Target

Java HotSpot(TM) Server VM (build 25.25-b02, mixed mode) This is written in 3 line. – Garage

You have 32 Bits Oracle – Target

This is most likely the issue because clicking the big red button on java.com/en/download automatically downloads the 32-bit. That was my issue. The 64-bit installation lives here: java.com/en/download/manual.jsp. – Rayborn
