Description Takashi Kajinami 2022-07-22 13:42:48 UTC

+++ This bug was initially created as a clone of Bug #2035406 +++

Description of problem:

Currently some tasks like paunch uses async mechanism in ansible.
These tasks have the first task to run a long running job asynchronously and the second task to run periodically check status of the first task.

Currently the second polling task is retried every 3 seconds but this interval is not guaranteed and it can be delayed for example there are multiple nodes, and more frequent interval causes more additional overhead. This makes the timeout detection happen very late.

In the real field we saw that the paunch task timed out in a controller node after 1 hour but ansible detected that after 2 hours.


Version-Release number of selected component (if applicable):


How reproducible:
Sometimes, when timeout is detected

Steps to Reproduce:
1.
2.
3.

Actual results:
Timeout is detected a while after the task times out

Expected results:
Timeout is detected immediately after the task times out
