Hi,

From the output, the RabbitMQ should be fine, right?

Hi Li,

I am not sure how to clear connection pool but even we faced a similar issued because rabiitmq server was not running.
Can you check if AMQP server is running properly or not?

Hi,

I’m installing Havana and meet a problem when run command “neutron agent-list”.
root at i2052247:~# neutron agent-list
Connection to neutron failed: Maximum attempts reached
Actually it would have same failure when run any neutron command.
I found bugs https://bugs.launchpad.net/neutron/+bug/1211915 and https://bugs.launchpad.net/nova/+bug/1229475/comments/14. Workaround is “ Forcibly clear connection pool“.
Does anyone know how to clear connection pool on Neutron/Havana?

Leon
