[AWIPS #LOE-610626]: EDEX server issues post upgrade to 18.2.1

Hello,

Sorry to hear you have been having some issues.

Yes, the EDEX we are running in the cloud is the same version that has been 
released to the public.

Can you elaborate on this? The ldmd.conf file is the same that we are using and 
is requesting all data from Unidata that comes from NOAAPort as well as the GFS 
1 degree global model data. The pqact.conf file is what shows what data are 
being stored in /awips2/data_store and processed by EDEX. What products do you 
think you are missing?

I'm not sure what issues are are having exactly. There were quite a few 
products that were added to LDM recently and it's possible your LDM queue is 
too small or your EDEX doesn't have enough memory to process everything. I'd be 
happy to work with you on this.

> RAP13_20210912_1900"

Do you use GFE? I believe GFE only re-processes GFS data and not other model 
data which is why that error is coming up. But you will still be able to look 
at the raw RAP model data from both the model menu and volume browser.
