Like almost everything other tools used in the Tuleap CI pipelines Cypress is executed inside a Docker container. As it is Electron/Chromium based, it is not really happy about it and sometimes the renderer process crashes by telling you it's out of memory.
By default, Docker container starts with a limit of 64MB of shared memory which can be a bit short when running a browser.
This a known issue when running Electron/Chromium inside a Docker container, you can read more about it in the Cypress's bug tracker:
