Geoffry, Information on the last, successfully-received data-product is stored on disk by a downstream LDM. It is only "shared", however with the corresponding downstream LDM of a subsequent LDM session (e.g., when the LDM is restarted). The white-paper on our LDM cluster describes multiple LDM "backend" hosts each receiving the same data streams. In such a situation, it's not necessary to share information on the last, successfully-received product. > > from the last successfully-received product (which it tracks) > > Where is that tracked?
