Processing a Message More Than Once

[BurakIsleyicii]

I have a single Service and I Publish and Subscribe the message to the queue in the same service. My purpose of use is to be able to do my asynchronous work in the service using this wonderful library. My problem is that when a message is published, it is recorded as Scheduled in the Database and it becomes Succeed after 4 minutes, but there is no error message or information. In this case, the Received also causes the same message to be processed with the same cap-msg-id value at 4 minute intervals. What could be the reason for this? I use CAP with PostgreSQL and RabbitMQ
