Hi I have same problem with 4.0.1 broker and I am working on this now trying to reproduce the problem. It happened for persistent queue that is using journaledJDBC persistence. I saw messages when I used browse command but for some reason consumers where not consuming them. After restart of the broker all stuck messages were consumed.
Can you reproduce your problem somehow? For now I was not able to reproduce this in my test environment.
