Re: [ldm-users] Downstream LDM Problems

Hi Steve & Gilbert, all.

Thanks for your response and help.

Some good progress.... first: silly, silly problem -- and a major oversight on 
my part -- even after all of the preaching re: a synchronized clock at the 
workshop.  The clock was set to CDT instead of EDT; none of the products were 
coming in until 1 hour later. Once we set the clock, everything began working 
as it should.  The minutes and seconds looked fine; I didn't notice that the 
hour was one off.    

The only outstanding issue I'm dealing with is the log file.

Yes, it is set to this "disabled".  I am Unix competent but not an expert.  If 
you have any advice here, I'd be thankful.  

Thanks again for taking the time to help us and have a nice weekend,
