Example failure:\nhttps://github.com/python/cpython/actions/runs/14813289395/job/41590700582\n\nAdditionally, the oldest tasks in such case are missing the `awaited_by` link to a task group context manager:\n`(2199028913760, 'Task-25', [[['echo_client_spam'], 2199050127392]])`\n\nA healthy task reports being under the task group context manager:\n`(2199056497056, 'Task-1997', [[['_aexit', '__aexit__', 'echo_client_spam'], 2199049603104]])`\n\nI looked at it on macOS ARM and Ubuntu ARM, but it does not reproduce despite re-running the test with `-F`. On GHA it happens often enough for us to notice on the PR.\n","author":{"url":"https://github.com/ambv","@type":"Person","name":"ambv"},"datePublished":"2025-05-03T20:45:55.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":1},"url":"https://github.com/133359/cpython/issues/133359"}
