-----------------------------------

             Summary: Duplicate Messages delivered over AMQPS connectivity 
using QPID Jars
                 Key: QPIDJMS-358
                 URL: https://issues.apache.org/jira/browse/QPIDJMS-358
             Project: Qpid JMS
          Issue Type: Bug
          Components: qpid-jms-client
    Affects Versions: 0.11.1
            Reporter: Pooja Arora


Hello Team,

We are using Apache QPID jars for AMQP  (JMS V1) to Azure Service Bus from IBM 
Integration Bus(IIB V9.0).

We use below jars :-
 # qpid-jms-client-0.11.1.jar
 # proton-j-0.14.0.jar
 # qpid-jms-discovery-0.11.1.jar
 # slf4j-api-1.7.21.jar
 # geronimo-jms_1.1_spec-1.1.1.jar

Below is our connection URL :

connectionfactory.qpidConnectionFactory = 
amqps://<server>:<port>?amqp.idleTimeout=150000&jms.username=<username>&jms.password=<password>&jms.receiveLocalOnly=true&jms.prefetchPolicy.all=1



We connect to predefined subscriptions on an Azure Service Bus Topic.

We have been using these jars for nearly a year now. Recently from past 2 weeks 
we are seeing some of the messages are delivered as duplicates with same JMS 
Message ID. Sometime same message is delivered 30-40 times within a second.

Also we use same connection URL to different subscriptions (PROD and UAT) to 
same topic from our UAT and PROD servers. So we receive same payload in both 
the environments. And we have noticed that these duplicate counts vary from UAT 
to PROD.

 

So looks like it can be some issue in the connection which is causing the 
duplicates. As we have had the upstream teams check complete data flow logic 
and we could not find any other place of duplicates.

 

Please suggest how we can debug this issue to find its RCA and related fix.
