I do have a "transparent duffy reuse" tool in https://github.com/cgwalters/centos-ci-skeleton which is used a lot in my jobs, but it generally avoids retaining machines for greater than an hour. Take https://ci.centos.org/job/atomic-fedora-ws-treecompose/50/console if you click through to https://ci.centos.org/job/atomic-fedora-ws-duffy-allocate/6699/console At: 22:09:11 Assigning host: n8.pufty.ci.centos.org (SSID=jenkins-atomic-fedora-ws-treecompose-50) Then at this point it hung and I finally aborted it: 22:32:45 Installing packages: 75% 23:53:14 Build was aborted So that host had only been assigned for less than 30 minutes. Is there anything relevant in the Duffy logs about this?
