Duly noted, thanks for the background info on this.

What does /proc/meminfo show over time - say every 15 minutes or so ?.
I think I will take some time to put this in a cron job, parse this into a database table, and then that will allow me to plot some pretty graphs. I'll get back to this thread with results from that when I have them.

If you can get rid of those tasks altogether, the buy-back may be better than you hope.
I bet this is because the JVM manages memory on its own and does not leave block management up to the kernel, garbage collection cuts both ways. Ironically, I found I get better performance from my Minikube by limiting its memory consumption.

jvm itself manages only its own memory (as any other process), jvm cannot manage swap, that is made by kernel only.

List the top 10 RSS (resident RAM) consumers:
Code:
ps -eo pid,user,rss,vsz,args | sort -k3,3n |tail
Run this every couple of minutes.
Which processes have growing memory?
