[opensuse-buildservice] repository delete requests not fully processed

The SRs 510894..510898 are in state accepted since three hours. All repositories are removed from the project. But packages are still being built for 13.1/13.2, which means SRs 510896/510897 are not fully processed. Why does this happen? I see this also in other projects. home:olh still lists results for "Fedora_21". Olaf
