I use the _bulk interfaces concurrent writes 10M stress test, but after
the memory footprint has been stubbornly high, unless I restart the
elasticsearch.
How to make JVM automatically frees memory.

Hi,
Are you seeing OOMs? Or long GC pauses? If not, don't worry - let the JVM
make use of the memory you let it use with -Xmx.
Conceptually similar to http://www.linuxatemyram.com/

Looks normal, especially under concurrent stress. You could try turning off
or stretching the refresh rate while you're indexing in concurrent bulks.
But let the JVM do it's job.

There is more than enough free memory on the heap. Why are you bothering?
