Hi Carl,

What's the fully-qualified hostname of the computer on which the LDM is doing

> Every two minutes LDM has been writing the information like the
> example below in our "ldmd.log" but it doesn't appear to be affecting
> data reception, at least not from what I've noticed.
> 
> Can you help me interpret what this means and what I need to do to clear
