The LDM wasn't started? Or it wasn't running?

pqact(1) shouldn't get a "permission denied" error when trying to save 
information on the last, successfully-processed product. What does a long 
listing of the file "/home/ldm/etc/pqact.conf.state.tmp" show? What about the 
parent directory?

I suspect the pqact(1) process responsible for the IDS|DDPLUS feed terminated 
normally because of the permission failure. Send me that output.
