Lack of RAM leads to crash during initial configuration

This is an install of the latest rocket.chat on an Ubuntu 22.04 LTS VM. Somewhere between steps 2 and 3 of the initial configuration screens, possibly occurring because I initially provided an email address not registered on cloud.rocket.chat (which would be nice to know), it seems that my RC instance has crashed:

Given the OOM reference, it looks like RC 6.3.1 can't manage with just 1GB RAM, which is documented at https://docs.rocket.chat/deploy/prepare-for-your-deployment/hardware-requirements — here's what I have

ubuntu@rocket-server1:~$ free
               total        used        free      shared  buff/cache   available
Mem:          992708      157612      677644         980      157452      680120
Swap:              0           0           0

Start with the deployment hardware-requirements page and the initial configuration flow for Rocket.Chat 6.3.1 on Ubuntu 22.04. Reproduce the one-GB, no-swap setup and inspect the service logs for the Node.js heap failure; done means establishing whether the documented requirement is inaccurate or the configuration flow should handle this condition.
