Louis,

Here is what I see in the LDM logs on atm:

Jun 26 12:49:34 atm.geo.nsf.gov angler[2484]: Connection from 
angler.larc.nasa.gov
Jun 26 12:49:34 atm.geo.nsf.gov angler(feed)[2484]: Starting Up:

error (errno = 5)
Jun 26 12:49:39 atm.geo.nsf.gov angler(feed)[2484]: Exiting

This tells me that atm gets the request from angler, OKs it, tries to
send it a product, but that the send fails.  This could be due to your
rpc.ldmd dying (or something else).  Can you send your
~ldm/logs/ldmd.log file?  This will help us determine what the problem is.

For our reference, what kind of machine are you running on (e.g.,
RedHat Linux 7.2; Sun Solaris SPARC 5.8, etc.)?  Did you do a binary or
source install (I think binary)?  We have seen instances of users
running on RH Linux 7.x where they needed to build their LDM from
source instead of using a binary, so, I am eager to find out if you fit
into this category.
