Daryl,

No such problem here for one of my feeds, which, for right now, is running 
just a primary site because I am testing a feed. BTW, if you upgraded to 
LDM 6.6.2, are you having problems with things not writing to 
disk correctly? Or not at all? Check this out:

And then this:

Many of the radar products I make on my website run from a script that 
calls that LDM entry above. As it turns out, in LDM 6, it means that the 
code that determines the canonical time of a product was not written 
correctly. It also means that your pqact entries using them may be wrong. 
I'm guessing that's your problem, as stuff has mysteriously stopped coming 
in or being saved. That's what happened to me when I upgraded to 6.6.2.
But 6.6.2 IS correct on how to do it, which means I am now seeing things 
work the way they should.

BTW, if you are doing a PRIMARY and ALTERNATE to a specific data feed, the 
lines, except for the site you are feeding from, have to match EXACTLY.
Otherwise, it will feed both feeds from both sites.
