Containerized springboot application not able to pick up new message from service bus queue

Question

We have a springboot application running in Azure Web App (using container docker)

The application is using "azure-spring-cloud-stream-binder-servicebus-queue" to connect to Azure Service Bus and process the queue.

If the queue was empty for some time, and when there is a new request coming into the queue, our application was not able to pick up the new request until we restart the application.

Has anyone encountered this before and can share their experience.

@Bean
public Consumer<Message<String>> onReceive() {
   return message -> {
   String msg = message.getPayload();
   //logic to process the msg
   };
}

Here is the POM.xml
