Description
With https://gitlab.suse.de/openqa/salt-pillars-openqa/-/merge_requests/320/diffs#0a0ec388f05cea3ca9a77dd911a33555ec192597_38_38 @mgriessmeier reduced the numofworkers for openqaworker2. Soon after we received an alert that several services on this machine fail. After closer investigation I see the following services failing:
● openqa-reload-worker-auto-restart@36.service loaded failed failed Restarts openqa-worker-auto-restart@36.service as soon as possible without interrupting jobs
● openqa-reload-worker-auto-restart@37.service loaded failed failed Restarts openqa-worker-auto-restart@37.service as soon as possible without interrupting jobs
● openqa-reload-worker-auto-restart@38.service loaded failed failed Restarts openqa-worker-auto-restart@38.service as soon as possible without interrupting jobs
● openqa-worker-auto-restart@37.service loaded failed failed openQA Worker #37
(Note: I don't understand why there is no openqa-worker-auto-restart@36.service nor no openqa-worker-auto-restart@38.service - is this a setup fail?)
These seem to be the related services which numofworkers got reduced by.
Example output for one of these services:

These services should handle a reduce of numofworkers more gracefully.

Same for openqaworker5:
● openqa-reload-worker-auto-restart@42.service loaded failed failed Restarts openqa-worker-auto-restart@42.service as soon as possible without interrupting jobs
● openqa-reload-worker-auto-restart@43.service loaded failed failed Restarts openqa-worker-auto-restart@43.service as soon as possible without interrupting jobs
● openqa-reload-worker-auto-restart@44.service loaded failed failed Restarts openqa-worker-auto-restart@44.service as soon as possible without interrupting jobs
● openqa-reload-worker-auto-restart@45.service loaded failed failed Restarts openqa-worker-auto-restart@45.service as soon as possible without interrupting jobs
openqa-worker-auto-restart@{42..45}.service seem to be missing all together on that machine. So is it already covered that numofworkers gets reduced and we see a race of some kind here?

I've reseted the failed units on openqaworker2 and openqaworker5, alert is good again.

I assume this should be In Progress?

Yeah, I just saw the OK

No, at max in "Workable". I do not plan to work on the service file fix. I just used the same ticket here to resolve the immediate alert

Looks like the worker was really just uploading remaining results, e.g.

This is expected. If the worker is terminated it stops the job but still uploads results (which also involves optimizing PNGs). I guess it is actually useful that logs are uploaded and the job's reason is set accordingly. However, it is indeed questionable to upload videos, images and other results of a job which is abandoned and restarted anyways. So I'd say the worker should still upload logs, mark the job as done (with reason quit) and restart it. That should not take too long and if systemd is still too impatient we can adjust the timeout within the service file. If you agree with that change we can add it as ACs and call the ticket workable.
