Comment 2 for bug 1835097

Hi,

If it started recently then most likely it's related with the recent deprecation of some config properties in oslo.messaging. Try to add "default_reply_retry=-1" under the group "oslo_messaging_amqp". The bottom line is that if you don't specify this property then the connection retry count by default is 0, i.e. it never tries to reconnect. So we need to make it infinite explicitly.

Let me know if it helps.
