The downstream LDM connected to the upstream LDM and asked the
upstream LDM to start sending data-products that arrived just
after the data-product with the given signature (an MD5 hashcode).
Unfortunately, that particular data-product was no longer in the
product-queue of the upstream LDM (because it had been removed in
order to make room for newer data-products).  The upstream LDM then
used the remainder of the selection criteria from the downstream
LDM to determine what data-products to send (typically, the
downstream LDM will request that the upstream LDM start sending
data-products from one hour ago).

This is a feature and not a bug.
