Could you forward the output of the following commands on a controller node? : rabbitmqctl cluster_status rabbitmqctl list_queues You won't necessarily see a high load on a Rabbit cluster that is in a bad state. On Wed, Jul 31, 2019 at 5:19 AM Grant Morley <grant@civo.com> wrote:
Hi all,
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:
ERROR oslo.messaging._drivers.impl_rabbit [-] [f4ab3ca0-b837-4962-95ef-dfd7d60686b6] AMQP server on 10.6.2.212:5671 is unreachable: Too many heartbeats missed. Trying again in 1 seconds. Client port: 37098: ConnectionForced: Too many heartbeats missed
The RabbitMQ cluster isn't under high load and I am not seeing any packets drop over the network when I do some tracing.
We are only running 15 compute nodes currently and have >1000 instances so it isn't a large deployment.
Are there any good configuration tweaks for RabbitMQ running on OpenStack Queens?
Many Thanks, --
