Memory in Docker is not released with eclipse-temurin:17-jre image

Question

We recently transitioned our application from Java 11 to Java 17. Following the DEPRECATION NOTICE in the OpenJDK Docker repository OpenJDK, we opted for eclipse-temurin and chose the eclipse-temurin:17-jre as the base image for containerizing our application.

The output of the kubectl describe command for the specific service is as follows:

We attempted to substitute the Docker base image with ibm-semeru-runtimes:open-17.0.9_9-jre, and it is functioning properly. However, due to other issues with OpenJ9, we are currently adhering to the use of eclipse-temurin:17-jre and finding the solution to free up the allocated memory.

Kindly advise if anyone has a solution to free up the allocated memory. Thanks
