RabbitMq consumer fails to receive from message from Queue

I am using RabbitMq 3.2.1 in Ubuntu 14.04. I have configured the exchange using nodejs module "amqp" like below.

 var options = {
            type: 'topic',          
            passive: false,        
            durable: true,         
            confirm: false,        
            autoDelete: false       
        };

I am also publishing message with the below configuration.

var options = {
                        mandatory: false,                   
                        immediate: false,                  
                        contentType: 'application/json',   
                        deliveryMode: 1,                    
                        priority: 1                        
                    };

With this, when I publish the message it all received by the consumer even-though if all the consumers were busy the message is waited in queue and it was consumed later by consumer when it is free.But the issue I am facing one of the message is never received by the consumer.

I have doubted that it all due to configuration I disabled for mandatory and immediate as false. But I need to make the message in queue if all consumers were busy and consumed later when it available.

Can anyone help what may be the issue?
