Description of problem: Error in "test_reuse_ip_address_with_other_fip_on_other_router" with duplicated floating IP. The test will create a FIP, then delete it and then create another FIP using the same IP address. The problem, as we can see in the following snippet, is that during the deletion and the creation again, another test requested a FIP and Neutron server provided **just the same IP address** (a case of bad luck): http://paste.openstack.org/show/794058/ Version-Release number of selected component (if applicable): RHOS-16.2-RHEL-8-20210420.n.0 How reproducible: Happens randomly. Occurs only when tests are running in several threads in parallel. Steps to Reproduce: 1. run test_reuse_ip_address_with_other_fip_on_other_router in parallel with other tests Actual results: In case of bad luck neutron gives deleted floating ip address (that test_reuse_ip_address_with_other_fip_on_other_router planned to reuse) to some other test and test fails. Expected results: Test succeeds. Additional info:
Verified on RHOS-16.2-RHEL-8-20210728.n.2 with python3-neutron-tests-tempest-0.9.0-2.20210528123644.el8ost.2.noarch. Verified that the test runs properly in parallel with other tests.
