+Kibana has a default memory limit that scales based on total memory available.  In some scenarios, such as large reporting jobs,
 it may make sense to tweak limits to meet more specific requirements.
 
 A limit can be defined by setting `--max-old-space-size` in the `node.options` config file found inside the `kibana/config` folder or any other folder configured with the environment variable `KBN_PATH_CONF`. For example, in the Debian-based system, the folder is `/etc/kibana`.
