Hi THREDDS list,

I've been massaging some services on top of a copy of the data here:
http://thredds.ucar.edu/thredds/catalog/grib/NPVU/RFC/catalog.html

Example dataset is here:
http://cida.usgs.gov/qa/thredds/qpe_realtime_catalog.html?dataset=cida.usgs.gov/fixed.ktua

We have some grib collections that are then wrapped so we can add custom
axes.

I had NetCDF Subset working fine but after modifying the underlying grib
collections to include less variables, OPeNDAP still works fine but I'm
getting 500s from the NCSS. Stacktrace is below.

Now when I change things back I still get 500s. Seems like there might be a
cache that's not clearing on restart that I don't know about? Any ideas?

Thanks!

- Dave
