From https://bugzilla.redhat.com/show_bug.cgi?id=1778428
We need to tune the default rabbitmq tcp listen backlog. Currently it defaults
to 128, but here's what happens:
Say we have 1500 total rabbitmq client connections spread across a 3 node
cluster, evenly distributed so each node has 500 clients.
Then, we stop rabbitmq on one of the nodes.
Now those 500 client connections all immediately fail over to the other two
node. Assume roughly even split, and each gets 250 connections simultaneously.
Since the tcp listen backlog is only 128, a large number of the failover
connections cannot connect and get ECONNREFUSED because the kernel just drops
them.
Eventually things retry and the backlog clears, but it just makes things noisy
in the logs and makes failover take a little bit longer.
Upstream docs discuss here:

tripleo-heat-templates
Heat templates to deploy OpenStack using OpenStack.
- Free software: Apache License (2.0)
- Documentation: https://docs.openstack.org/tripleo-docs/latest/
- Source: https://git.openstack.org/cgit/openstack/tripleo-heat-templates
- Bugs: https://bugs.launchpad.net/tripleo
- Release notes: https://docs.openstack.org/releasenotes/tripleo-heat-templates/
Features
The ability to deploy a multi-node, role based OpenStack deployment using OpenStack Heat. Notable features include:
- Choice of deployment/configuration tooling: puppet, (soon) docker
- Role based deployment: roles for the controller, compute, ceph, swift, and cinder storage
- physical network configuration: support for isolated networks, bonding, and standard ctlplane networking
Directories
A description of the directory layout in TripleO Heat Templates.
- environments: contains heat environment files that can be used with -e
on the command like to enable features, etc.
- extraconfig: templates used to enable 'extra' functionality. Includes
functionality for distro specific registration and upgrades.
- firstboot: example first_boot scripts that can be used when initially
creating instances.
- network: heat templates to help create isolated networks and ports
- puppet: templates mostly driven by configuration with puppet. To use these
templates you can use the overcloud-resource-registry-puppet.yaml.
- validation-scripts: validation scripts useful to all deployment
configurations
- roles: example roles that can be used with the tripleoclient to generate
a roles_data.yaml for a deployment See the roles/README.rst for additional details.
Service testing matrix
The configuration for the CI scenarios will be defined in tripleo-heat-templates/ci/ and should be executed according to the following table:
- | scn000 | scn001 | scn002 | scn003 | scn004 | scn006 | scn007 | scn009 | scn010 | non-ha | ovh-ha |
