Memory is not getting released/Memory Leak after execution of delete process instances

Hi, I am using Camunda 7.11. I deleted 180k process instances one by one via Delete process instance REST API and it took 28hrs to complete. Now Camunda CPU became normal but Memory utilisation is still at its peak after 5hrs of completion of execution. Reserved 3GB for Camunda. Could you guys help me to understand where my configuration went wrong and how should I resolve this issue ?

Hi any update on this?

Hi Guys, it would be a great help to me if you guys help me to resolve this issue as i am facing this issue since so many days. All i am doing is right now restarting the pod as a temporary solution.

Thanks in Advance.
