Justin,

I don't like the fact that your LDM log file seems to have the following:

Jun 9 05:39:46 vm-lnx-ncodfdev srh-ls-cpnrs2.srh.noaa.gov [6649] INFO: 
Connected to upstream LDM-6 on host srh-ls-cpnrs2.srh.noaa.gov using port 388
Jun 9 05:39:46 vm-lnx-ncodfdev srh-ls-cpnrs2.srh.noaa.gov [6649] INFO: 
Connected to upstream LDM-6 on host srh-ls-cpnrs2.srh.noaa.gov using port 388*

Was this a cut/paste typo?
