Issue/Introduction

RabbitMQ consumers are not able to consume messages until after a restart.
This KB is applicable to all versions of RabbitMQ.

Resolution

Here are some recommendations to resolve the issue:
 

1. Please make sure that the consumers are attached to the queue or queues in question.
2. If the consumers are already attached to the queue(s), then check if the issue is resolved by restarting the consumers.
3. If restarting the consumers doesn’t resolve the problem, then please file a ticket with VMware Tanzu support.
4. If restarting the consumers resolves the problem, then this is a consumer code-related issue and not related to RabbitMQ.
5. We recommend you to review the Reference links below, which include the reconnect logic, etc., to provide the appropriate changes in your consumer code.
