The log messages show the notifyme(1) process connecting,
requesting data, and then the upstream LDM failing to receive
a response from the notifyme(1) process after sending it
the metadata of a data-product.  The log messages indicate
that the RPC call from the upstream LDM to the notifyme(1)
process did not return (i.e., that the upstream LDM wasn't
able to obtain an acknowledgment of receipt from the
notifyme(1) process.

I've never seen this before and am at a loss to explain it.

Mike?
