Messages from asyncio about "Task was destroyed but is is pending"

[marioaag]

I have been using Avocado from a long time with a direct calls to the API without any problems but now changing from python3.10.11 to python3.11.9 it started to display messages at the end from asyncio. Also tried with python3.14 and is the same behavior.

2026-03-06 14:56:46 -E- BlueGen: Task was destroyed but it is pending!
task: <Task pending name='Task-1' coro=<StatusServer.serve_forever() running at /Users/mario/Library/Python/3.11/lib/python/site-packages/avocado/core/status/server.py:44> wait_for=<Future cancelled>>
2026-03-06 14:56:46 -E- BlueGen: Task was destroyed but it is pending!
task: <Task pending name='Task-2' coro=<Runner._update_status() running at /Users/mario/Library/Python/3.11/lib/python/site-packages/avocado/plugins/runner_nrunner.py:255> wait_for=<Future pending cb=[Task.task_wakeup()]>>

I have been trying to reproduce it isolated without success and I didn't find anything related in the logs.

Any idea of what could be happening here or where to look?

@richtja, @clebergnu do you have any suggestion here?

Hi @marioaag not sure. Can you be more specific about the API calls which you are using and causing this?

Hi @richtja,

In in essence I'm doing multiple calls to the avocado job.run() with multiple different runners and suites generated by my self using TestSuite and Runnable methods. Something like this but more elaborated with extra conditions, etc.
