lappin,

Could you look for two programs on the machine: das2ldm_nexrad and
das2ldm_nowrad? On our WSI box we have 2 lines in the LDM etc/ldmd.conf
file to get the products:

exec    "/opt/das2ldm/bin/das2ldm_nexrad -l /dev/null -q
/opt/ldm/data/ldm.pq"
exec    "/opt/das2ldm/bin/das2ldm_nowrad -l /dev/null -q
/opt/ldm/data/ldm.pq" 

These program take the place of pqing program to get the products into the
LDM.  If you don't have these programs, how do you get the products?  Also
I would contact WSI about this issue. We have worked with WSI, so they
should have the configuration needed to get the products into the LDM.
They might have changed the configuration because our WSI box is about 5
years old. If the configuration is different, can  you let me know for any
future questions.

Thanks,
Robb...
