Is this recycle of soft reference?


(Rukia) #1

In this picture, there is a steep drop in JVM Heap graph between 8 a.m. to 9 a.m.. I am wondering the reason of this.

My log entered smoothly at that time (8 a.m to 9 a.m).

What is that? Is recycle of soft reference in Java?
This is important cause I am investigating how much heap size is suitable for my service.

Version of Elastic stack is 6.3.1, and my server os is
