Start with the roachtest README and the linked test artifacts at /artifacts/import/pause/distmerge=false/nodes=4/run_1; inspect the timeout logs and Grafana dashboard for the four-node run. Trace the import/pause test entry point in pkg/cmd/roachtest and identify why it exceeds 14 hours. Done means the failure cause is addressed and the test completes successfully on a rerun.
