Description Arie Bregman 2017-07-13 16:55:29 UTC

Description of problem:

In latest build (OSP 12, 3 cont, 2 comp, non-containerized) the following tests failed:

*tempest.scenario.test_network_v6.TestGettingAddress.test_multi_prefix_slaac
*tempest.scenario.test_network_v6.TestGettingAddress.test_dualnet_multi_prefix_dhcpv6_stateless

In some builds, one of the tests fails in other both. It's not persistent on a number of tests failing but there is at least one test from "tempest.scenario.test_network_v6.TestGettingAddress" which fails

Version-Release number of selected component (if applicable): openstack-neutrton-11.0.0-0.20170710190714.a51271d.el7ost.noarch


How reproducible: 100%


Steps to Reproduce:
1. Deploy non-containrized HA (3 controllers, 2 compute) deployment 
2. Run neutron API tempest tests

Actual results: test failed with the traceback above


Expected results: test passed successfully


Additional info: non-containerized deployment

It seems to happen when a subnet is created. I wonder if this is a duplicate of bug 1470784.

Maybe related to https://review.openstack.org/#/c/396718, need to look at when it hit our jobs first.
