We are moving our JDK 1.8v131 JVM servers to Kubernetes/Docker environment.
We have few JVM servers running in stand alone VMs and few running Kubernetes/Docker environment and both types are present in production.
With the same load Kubernetes/Docker JVMs are running out of memory whereas JVMs in VMs are running fine without issues.
We used exact SAME JVM parameters for running in VM & Container.

Any ideas how to fix this issue?

Here are the options:
