Comment 3 for bug 1952414

I think everyhing boils down to get_network_addresses()[0] , according to the docstring it may return any of these lists:

[(address_in_net_a, hostname_in_net_a),...]
[(address_in_net_a, vip_in_net_a),...]
[(address_in_net_a, address_in_net_a),...]

For the job I am troubleshooting neutron-api has a single unit (non-HA), so we have security that there is no vip set which rules out the possibility of return a list like the second one. So what if one run of get_network_addressess() returned a list like the first one while other runs returned a list like the third one?, I have no evidence, but it would explain the behavior.
