Hi all, as per grafana [1] the functional job is broken. Looking at logstash [2] it started happening consistently since 2017-08-03 16:27. I didn't find any particular patch in Neutron that could cause it. The culprit is that ovsdb starts misbehaving [3] and then we retry calls indefinitely. We still use 2.5.2 openvswitch as we had before. I opened a bug [4] and started investigation, I'll update my findings there. I think at this point there is no reason to run "recheck" on your patches. Thanks, Jakub [1] http://grafana.openstack.org/dashboard/db/neutron-failure-rate?panelId=7&fullscreen [2] http://bit.ly/2vdKMwy [3] http://logs.openstack.org/14/488914/8/check/gate-neutron-dsvm-functional-ubuntu-xenial/75d7482/logs/openvswitch/ovsdb-server.txt.gz [4] https://bugs.launchpad.net/neutron/+bug/1709032
