Review comment:
Thanks for the edit!
It seems that [On native Linux, Docker can use all available host memory](https://stackoverflow.com/questions/62649255/how-to-increase-check-default-memory-docker-has-on-linux). So the memory limit seems to be a MacOS thing. It can be adjusted using the [Docker Desktop](https://docs.docker.com/desktop/mac/) for mac.
This is worth noting because when we're on Linux (Ubuntu) we will be happy as clams, but then we get slammed when we do the same thing on MacOS.

Review comment:
```suggestion
Docker needs at least 6 GiB of memory available for the Druid cluster. For Docker Desktop on Mac OS, adjust the memory settings in the [Docker Desktop preferences](https://docs.docker.com/desktop/mac/). If you experience a crash with a 137 error code you likely don't have enough memory allocated to Docker.
```
Thanks for the idea @paul-rogers .
