<p class="MsoNormal">This has been discussed at great length; here are a couple of links that lead to interesting threads:<br>
<br>
<a href="https://lists.openstack.org/pipermail/openstack-discuss/2021-November/026074.html">https://lists.openstack.org/pipermail/openstack-discuss/2021-November/026074.html</a><br>
<a href="https://lists.openstack.org/pipermail/openstack-discuss/2020-August/016362.html">https://lists.openstack.org/pipermail/openstack-discuss/2020-August/016362.html</a><br>
<br>
There used to be a useful document here:<br>
<a href="https://wiki.openstack.org/wiki/Large_Scale_Configuration_Rabbit">https://wiki.openstack.org/wiki/Large_Scale_Configuration_Rabbit</a><br>
<br>
That link now points to the “Large Scale SIG” home page. Does anyone know where the useful RMQ document is? I assume that it is buried somewhere under “Large Scale Journey.”<br>
<br>
The bottom line is that, by default, kolla-ansible enables replication but not durable-queues, which is an unstable configuration. I believe that this may have been fixed in a newer version; we are on Train.<br>
