[LDM #UGB-524529]: No LDM server running?

Hi Andy,

Is this the MADIS data?

> Any ideas on what could be causing this?

If the data files being inserted into the upstream LDM queue are OK, then
they should be received without error.  Some questions come to mind:

- what is the typical size of the gzipped netCDF files you are receiving
- what is the rate of receipt of these files
- what is the size of your LDM product queue
- how are you processing the files (i.e., pqact.conf entry(ies) that do the
  processing) (I am interested to see if you are FILEing the files before
  trying to uncompress them.)
