Subscriber dropping samples (can't keep up ?)

I have a publisher/subscriber pair (created usingĀ  DDSTheParticipantFactory->create_participant_from_config). The subscriber uses a dynamic reader and waits on DDS_DATA_AVAILABLE_STATUSĀ to receive new data from the publisher. At publication rates of > around 5 Hz, the subscriber begins to "miss" new samples, getting worse as the publication rate is increased. It will typically go for 1 - 3 seconds without seeing new samples, then receive a short burst (2 - 10) of consecutive samples, and repeat this cycle.
