Do we run the app with limits?

Start with the linked GitHub Actions run and the traceback locations in gprofiler/metadata/versions.py and gprofiler/utils/__init__.py. Investigate the attach-maps failure, including whether the app runs with limits and why /proc/1/exe --version receives SIGKILL after the three-second timeout. Done means the resource-limit cause is established and the flaky test has a defined resolution.
