Housekeeping only kicks in when a project is analyzed – there’s no process in the background waiting for the right amount of time to pass. On new project analysis (of any branch), your old branches / PRs will be cleaned up!
Hi,
Welcome to the community!
Only the latest version of SonarQube Community Build is considered active, so you’ll need to upgrade and see if the situation is still replicable before we can help you.
If you have a screenshot like before where a new analysis hasn’t triggered the cleanup, I’d love to see it! But this screenshot just shows analyses done 11 months to a year ago.
