From the link you gave, webui is at Version 4.6.1534341932.1ded71aa
There is some particular reason to run such old worker? Basically seems 1 year old https://github.com/os-autoinst/openQA/commits/89b04ed8

- File openqa-resource-allocator.log openqa-resource-allocator.log added
- File openqa-scheduler openqa-scheduler added

- File openqa-webui.log openqa-webui.log added
- File openqa-worker.log openqa-worker.log added
There is no reason, I have updated to the last package version and rebooted the system. How can it be that the worker is so old?

Sorry, I copied the wrong version number.

looks like one of the instance is downloading the iso.
Aug 16 10:54:15 sergio-latitude worker[7316]: [info] [pid:7316] CACHE: Being downloaded by another worker, sleeping.
If the worker is actually not downloading it - did you by any chance brutally killed one of the workers instances while the download was in progress? if so you might need to clean up the cache

- Description updated (diff)
It may be realated to the shutdown of the SRV2. My Loewe's workers were down. That may have caused the issue.

Updating the cache database is a workaround for the problem, but it can still happen.
The worker cache needs to evolve and be decoupled so that only one thing is doing the download (the tests are a separate story)

Somehow this is happening even more often: https://openqa.suse.de/tests/1999655 on workers that were not killed even...

Was cache cleaned up on ow6 since https://progress.opensuse.org/issues/39980 ? if not, then it might still be locked since

- Assignee set to EDiGiacinto
Looking at it - we can maybe reduce (not fix) the impact of the bug temporarly with a workaround before going to move the cache as a service (which requires more time)

Pr with workaround (which was meant to be merged if the problem is more frequent): https://github.com/os-autoinst/openQA/pull/1764
But that won't spare deadlocks when workers get sigkilled - for a long term solution which is still being worked on, see: https://github.com/os-autoinst/openQA/pull/1783 and #39980
