             Summary: Routes messages to broker with large header
                 Key: DISPATCH-2254
                 URL: https://issues.apache.org/jira/browse/DISPATCH-2254
             Project: Qpid Dispatch
          Issue Type: Improvement
          Components: Routing Engine
    Affects Versions: 1.16.0
         Environment: PROD
            Reporter: Ekta


Hello,

Below is what our application and messaging architecture looks like. 

We have  a Microservice --> nlb --> qpid ---> amq brokers (Master/slave)

We recently saw a scenario where a java microservice application pushed a few messages to our amq brokers where the message was containing a larger header than the normal size header, which led to a very big disaster and caused our whole amq env to shutdown. To avoid such cases like these, is there a way to discard a message or handle this situation at the qpid layer so that it does not endup on our brokers as qpid for us is basically acting like a proxy and simply routes the traffic to brokers. Though the broker rejects this large header message but still stores it in its memory and goes in a infinite loop and keeps retrying the process the message which causes a over head on the brokers and immediately all the brokers go in shutdown state. 

If there a way to handle this a little better on on amq incase it is not possible on qpid layer.  Would appreciate any feedback if anyone have faced this issue before. 

Thanks
