Azure service bus queue only receiving 450 messages at a time

Does Azure have some kind of limitation in terms of batch items received? The following code is only retrieving 450 messages despite being asked for more:

QueueConnector.MyQueueClient.ReceiveBatch(1000, new TimeSpan(0, 0, 10));

I've tried increased times, but it doesn't have any impact--450, every time. This appears to be the recommended way in the Azure SDK docs of batch receiving.

Note: there are tens of thousands of items in the queue.

The count passed to the ReceiveBatch is an upper bound and that is also mentioned right in the docs, so this is expected behavior. Service Bus will release a batch based on message availability or batch size. Batches are capped at 256 kByte for send and receive. For SendBatch, that's also said in the docs.
