So, yeah, part of this is my fault. :( If you look at https://koji.fedoraproject.org/koji/taskinfo?taskID=36131065 you will note that there are 4 buildroots listed. That means the build was restarted 4 times. Likely this happened when I was installing/updating/shuffling builders around there. Sorry about that. That said, it still should have finished long ago. The current state of s390x builders: buildvm-s390x-01 to 14 are all the existing Z/VM instances we have had for a long while. Likely we are going to keep them for a while until we are sure the kvm instances are reliable and happy. buildvm-s390x-15 to 24 are new kvm instances. They have a higher 'weight' than the others and from my testing are much faster. Your build seems perhaps stuck in tests? I've freed it (again) and it's now running on buildvm-s390x-22 (a kvm instance). Lets see how it does there. I will in the meantime update/reboot the Z/VM instances. kevin
