In our experience, it's actually quite common that an RDS shutdown (or even just applying parameter changes) can take a while. What's particularly concerning is that it's not predictable, and that can make it hard to schedule and manage maintenance windows. What we were told previously is that RDS queues the operations, and it can take a variable amount of time for the operation to be worked on from the queue. Is that not the case?
