Yes this is a bug. The 1460 fix doesn't handle the count correctly. look at the method public void removeAllReferences() throws Throwable { synchronized (lock) { .....//removing all non scheduled msg from memory. deliveringCount.set(0); } //clear sch clearAllScheduledDeliveries(true); So the count will go minus. I should have put it before the deliveringCount.set(0); and the count should be OK. Sorry, I'll correct it.
