Fixed In Version: openstack-neutron-7.1.1-5.el7ost
Doc Type: Bug Fix
Doc Text:
Previously, if all controller nodes restarted at the same time, it would cause all amqp (rabbitmq) servers to also restart. This caused the connection between Neutron agents and the amqp servers to appear to hang until timed-out, while the time-out length is linear (60 seconds, then 120, then 240... limited at 600), preventing agents from receiving any events until the timeout expires. With this update, the timeout mechanism in the specific event that tries to connect between the agents and the neutron-server was changed to always be 60 seconds. Now, if the connection hangs because of a restart of all controller nodes, the agents recover quicker (up to 60 seconds after the controllers fully start again).
