Hi @Toniotti Thanks for reporting that. Because you are using "spring-cloud-azure-starter-servicebus-jms", can you open up a new issue with detailed information, like how to reproduce? you can tag that issue...
**Reason** 1. The `.parallel(processorOptions.getMaxConcurrentCalls(), 1)` will always prefetch 1 more message. 2. When subscriber of `ServiceBusReceiveLinkProcessor` call `onSubscribe()`, it will request 1 more message. And `ServiceBusReceiveLinkProcessor#onNext()` add the link credit.
The follow-up 412 error issue is tracked in #31672. We will work a fix for it.
