Elasticsearch RAM usage on local install

[VlaK0r]

Hello!
Thank you for your hard work.

The instance is installed on raspberrypi (Debian GNU/Linux 12 64bit / Linux 6.1.0-rpi8-rpi-v8)

The installation uses a large amount of RAM.
But after the installation is finished, the RAM remains occupied, plus it starts to fill up SWAP.
If you stop the db_elasticsearch container, then the consumption of RAM drops significantly.

Please tell me, is this the normal state of a working NewsBlur? Or is something not working correctly?

  db_elasticsearch:
    container_name: db_elasticsearch
    image: docker.elastic.co/elasticsearch/elasticsearch:7.16.3
    mem_limit: 512mb

I found this line in the file docker-compose.yml
But it turns out that this restriction does not work.

I read the documentation on elasticsearch.
mem_limit: 512mb - not right.
It is necessary to specify in bytes mem_limit: 536870912
Everything is working correctly now.
