[THREDDS #GWM-344487]: Thredds Error on WMS Request

Hi Guan,

I have not yet been able to duplicate the problem. Are you getting the error 
when the entire dataset lat/lon is requested or only when subset requests are 
made? But then some subset requests do work?

Is this happening for all your datasets? The example URL you gave looks like it 
is for an aggregated or NcML modified dataset. Are you seeing this problem only 
for aggregated/NcML datasets or for other datasets as well.

Yes, if you could send sample data that would be great. Please also send the 
configuration you are using for the dataset (if it is aggregated/NcML dataset).

Could you also try the URL you gave below but replace "VERSION=1.1.1" with 
"VERSION=1.3.0" and see if you still get the same error?

Thanks,

Ethan
