reproducible¶

TBD

problem¶

Is the locked database a symptom or the problem causing the worker to be stuck?

This is the output when stopping the worker

Jun 04 08:34:09 openqaworker2 systemd[1]: Stopped openQA Worker #7.

Why the "[ERROR] 404 response: Not Found" when trying to stop the worker?

When there is no output of "[DEBUG] Update status so job is not considered dead." in the logfile for three days shouldn't the worker be considered dead by the scheduler?

workaround¶

Restart the worker
