Description Slawek Kaplonski 2023-07-19 09:13:15 UTC

I have seen that in the CI job https://rhos-ci-jenkins.lab.eng.tlv2.redhat.com/job/DFG-network-neutron-17.1_director-rhel-virthost-3cont_2comp-ipv4-geneve-gate-ovn/367//artifact/tempest-results/tempest-results-neutron.1.html where one test failed due to error 500 returned from neutron server.

In the neutron logs http://rhos-ci-logs.lab.eng.tlv2.redhat.com/logs/rcj/DFG-network-neutron-17.1_director-rhel-virthost-3cont_2comp-ipv4-geneve-gate-ovn/367/controller-0/var/log/containers/neutron/server.log.1.gz I found stacktrace:
