[IDD #DSF-516290]: problem with NNEXRAD feed from idd.unidata.ucar.edu

Hi Greg,

> contributing to this problem?

I don't think that switching where the NEXRAD Level III products get
written should cause the receiving LDM process (rpc.ldmd) to 
not communicate well.  The switch might, however, have resulted
in the products getting written slower.  This depends, of course, on
how fast writes to your RAID is.

There is nothing magic about 10Z on our side.  Do you have anything
special happening at this time?

I am moving this question to a separate GEMPAK inquiry.

Cheers,
