Last modified: 2016-07-12 14:35:19 EDT
Description of problem: Connecting AMQP to port 5000 creates infinite reconnect loop that blocks workers. This is the port that is default in 5.6 and is used mainly for keystone. Version-Release number of selected component (if applicable): 5.6.0.6 How reproducible: 100% Steps to Reproduce: 1. Add an Openstack provider adding the AMQP hostname as the same as the Default hostname and leaving the port as 5000 2. 3. Actual results: Inventory never completes, provider cannot be deleted, new providers cannot be created. Expected results: Connection error is handled, logged and warning shown in UI. Additional info: E, [2016-05-17T07:42:34.597712 #4898] ERROR -- #<Bunny::Session:0x5ea41b0 guest@xx.xx.xx.xx:5000, vhost=/, hosts=[1xx.xx.xx.xx]>: Got an exception when receiving data: IO timeout when reading 7 bytes (Timeout::Error) W, [2016-05-17T07:42:34.598236 #4898] WARN -- #<Bunny::Session:0x5ea41b0 guest@xx.xx.xx.xx:5000, vhost=/, hosts=[xx.xx.xx.xx]>: TCP connection failed, reconnecting in 5.0 seconds These log messages continually show up

We need to set reconnect limit and we need to disable reconnect for validation. So reconnect is set only for connection created by worker, that should be consuming events.
