Since Elasticsearch ~7.17 Elasticsearch takes 50% of your memory by default.  
You can adjust this by configuring the heap size of it - the official elasticsearch documentation should help you - 1-2 GB memory should be reasonable enough.

In my tests you shouldn’t go below that.

Thanks for the response. Could you tell me where in the docker config I would go to adjust that?

No not really sorry. I believe you can set environment variables in docker and that should do the trick.

Just in case anyone else runs in to this issue the following in docker-compose should fix it:

```auto
    environment:
      - "ES_JAVA_OPTS=-Xms4096m -Xmx4096m"
```
