The number of slots is given by the sum of "nprods", "nfree", and "nempty", which in both cases is 488281. Your downstream product-queue has more slots on the free list. > There are a couple of fundamental sorts of information I'd like to get a > handle on.

The command "pqact -vl- >/dev/null" will list the products in the queue. > I don't think there's a way to get this information.

The product-queue deletes the oldest data-product first in order to make room for a new data-product. The pqcat(1) command previously mentioned lists the contents of the product-queue in temporal order, so the first product listed is the oldest product. > Thanks. > > -- > ==Leonard E.
