There could be several reasons for unanticipated decreases in publication and acknowledgement by consumers in a RabbitMQ queue, including:
Slow consumer processing speed: If the consumer is overwhelmed with the incoming messages, it may not be able to process them in a timely manner, causing the queue to fill up and slow down the publication and acknowledgement process.
Network connectivity issues: If there are connectivity issues between the publisher and the RabbitMQ server or the consumer and the RabbitMQ server, it may cause delays or failures in publication and acknowledgement of messages.
Delivery mode settings: RabbitMQ provides delivery modes that influence how messages are persisted on disk. If the delivery mode is set to "transient", it means messages are not persisted on disk, and if the server goes down, messages are lost. This can result in unanticipated decreases in publication and acknowledgement of messages.
Queue configuration: If the queue is configured improperly, it may not be able to handle the volume of messages being published to it, leading to unanticipated decreases in publication and acknowledgement.
Error handling: If errors occur during the processing of messages, they may not be acknowledged or re-queued, leading to unanticipated decreases in publication and acknowledgement.
RabbitMQ server overload: If the RabbitMQ server is overloaded with too many incoming messages, it may not be able to keep up with the volume, resulting in unanticipated decreases in publication and acknowledgement.
