Comment 0 for bug 1735823

We are noticing recurring failures in the gate under CentOS and OpenSUSE across Devstack and Packstack jobs on the master branches.

Example failures:
- CentOS Devstack: http://logs.openstack.org/46/523646/1/check/legacy-tempest-dsvm-neutron-full-centos-7/5bf092c/job-output.txt#_2017-11-29_03_02_38_031560
- OpenSUSE Devstack: http://logs.openstack.org/23/522423/7/check/legacy-tempest-dsvm-neutron-full-opensuse-423/b6768d7/job-output.txt#_2017-11-27_21_53_13_340319
- CentOS Packstack: http://logs.openstack.org/14/516714/1/check/packstack-integration-scenario002-tempest/7ba8d06/job-output.txt.gz#_2017-10-31_17_55_39_845816

They all fail with the same stack trace:
