However, this has some frequently unexpected ramifications. Run the game with the bat. The above parameters increase the InitialHeapSize (-Xms) to 4GB (4096 MB) and MaxHeapSize(-Xmx) to 6GB (6144 MB). If the Java heap itself is small (-Xmx), the JVM may allocate it in the lower 4GB of address space along with the Class Pointers and Monitors/Locks. What is minus XMS minus XMX while starting JVM?

It's recommended to set these values to be the same so the heap size isn’t contracting and expanding during the life cycle of the JVM — as resizing takes up overhead and can decrease overall performance. The default value is 25% of -Xmx and when -Xmx is set to -Xms the nursery will never grow. This leaves 4GB free on the container, which is usually fine, but sometimes under load I see the docker container exited (and java process.
