>             Project: Qpid JMS
>          Issue Type: Bug
>          Components: qpid-jms-client
>    Affects Versions: 0.11.1
>            Reporter: Pooja Arora
>            Priority: Critical
>
> 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.
