[LDM #YEX-392060]: ldm question

Michael,

It's too bad that you can't log into the upstream system as the LDM user. That 
would help a lot.

Here are the log messages from the downstream LDM process on your system that 
requested MRMS data:

They show that it started at 13:06:28 and requested the last hours worth of 
data. About 1 hour and 40 minutes later (at 14:46:00) the connection to the 
upstream LDM broke and was re-established within a second. All this behavior 
looks perfectly normal.

Did MRMS data-products continue to arrive after 14:46:01?
