Hi Marcus,

re:
> Our LDM has been getting data outages lately,

We had some hiccups this past weekend when the machine rooms
that house a number of our outward facing services were taken
down.  Service was mostly up by midday on Monday, but there
have been some lingering problems with the machine we collect
real-time IDD statistics (rtstats.unidata.ucar.edu).

Being able to send real-time stats back to us should not have any effect
on your ability to be fed data.

This is indeed a problem.  It typically means, however, that there is some
problem in the network connection between you and idd.unidata.ucar.edu.

Questions:

- is your machine still having problems receiving data from 
idd.unidata.ucar.edu?

- did you try restarting (ldmadmin restart) your LDM to see if the problem
  would clear?

I will check the real server backend machines of the idd.unidata.ucar.edu
cluster to see if log messages shed more light on what may be going on
with the feed(s) to you.

Cheers,

Tom
