-------------------------------------
Try with 4.6.0 that has CAMEL-20266
> camel-azure-servicebus: Consumer fails to acknowledge messages
> --------------------------------------------------------------
>
> Key: CAMEL-20660
> URL: https://issues.apache.org/jira/browse/CAMEL-20660
> Project: Camel
> Issue Type: Bug
> Components: camel-azure
> Affects Versions: 4.4.0, 4.4.1, 4.5.0
> Reporter: Dylan Piergies
> Priority: Major
> Fix For: 4.x
>
>
> We have observed issues with the Service Bus consumer from Camel 4.4+ where
> consumed messages are not acknowledged/completed correctly and landing in the
> dead-letter queue, despite the Exchange having successfully delivered the
> message to its destination.
> Our routes all follow the general form:
> {{from(azureServicebus(...))}}
> {{ // ...}}
> {{ .to(https(...))}}
> {{ .log("Message delivered to...");}}
> In our logs, we are seeing the message from the final {{log}} EIP and we can
> confirm that the message has been delivered to the destination service, but
> this is often followed by a log message from the
> {{com.azure.messaging.servicebus.ServiceBusReceiverAsyncClient}} logger:
> {{Cannot perform operation 'completed' on a disposed receiver.}}
> We then see many of these messages arriving in the DLQ, once the retry count
> is exceeded.
> The issue is difficult to create a reproduction for: it is intermittent and
> occurs most frequently during a spike in message volumes.
> The issue disappears after downgrading Camel to 4.3.0.
> Whilst we do not know the root cause for sure, we suspect this may be a
> defect of CAMEL-19262, occurring if the client is closed and recreated while
> an Exchange is in flight.
