<p>Hi all,</p>
<p>We are randomly seeing slow instance launch / deletion
times and it appears to be because of RabbitMQ. We are
seeing a lot of these messages in the logs for Nova and
Neutron:</p>
<p>ERROR oslo.messaging._drivers.impl_rabbit [-]
[f4ab3ca0-b837-4962-95ef-dfd7d60686b6] AMQP server on <a
href="http://10.6.2.212:5671" target="_blank"
moz-do-not-send="true">10.6.2.212:5671</a> is
unreachable: Too many heartbeats missed. Trying again in 1
seconds. Client port: 37098: ConnectionForced: Too many
heartbeats missed</p>
<p>The RabbitMQ cluster isn't under high load and I am not
seeing any packets drop over the network when I do some
tracing.</p>
<p>We are only running 15 compute nodes currently and have
>1000 instances so it isn't a large deployment.<br>
</p>
<p>Are there any good configuration tweaks for RabbitMQ
running on OpenStack Queens? </p>
<p>Many Thanks,<br>
</p>
