[Azure Service Bus] JMS messages getting dead-lettered

CSharpArtisan, thanks for your comments. You are correct on the peek-lock mode, lock duration and max deliver count. Users are more likely to see messages in the DLQ when prefetch is turned on, especially when the consumer has slow performance. Many users are not aware of the fact that prefetch is enabled by default in Qpid. You can read more on prefetch following the link in the article to see my points.
