RAM issue in Ray

How to fix the constantly growing memory usage of ray?
Why RAM keep on exceeding to huge amount and then it show memory issue while performing some ray tune functions? We even though close and shutdown ray in other notebooks but then also memory do not decreases.

Which process is the cause of the memory leak?
