Are you certain that those messages have actually been taken off the
queue?
When I ran into problems, it was because the queue would only queue 1000
messages, and I didn't have a reader pulling entries off the queue.
(Second order problem: I *did* have a reader, but the writer was
flooding it with more messages than it could cope with.)
You could increase the memory space used for the queue, thereby
increasing the number of messages queueable, but if that merely means
you shift the problem 30 seconds down the road, it's not a particularly
useful solution.
