Dear THREDDS community,
I'm having difficulty fixing an error with one of our FMRC datasets in TDS and
was hoping to get some help. This dataset is an FMRC aggregation that scans a
directory for a new file twice a day (recheckEvery="12 hours"). We have other
FMRC model datasets doing the same setup with no problems. However, this one is
not accessible each morning when I go to check on it. The only way I've figured
out how to clear up the problem is to restart Tomcat, and then the dataset is
accessible again. Before restarting Tomcat, though, when I click on the
following link:
http://oos.soest.hawaii.edu/thredds/dodsC/hioos/roms_forec/HI-ROMS_Forecast_Model_Run_Collection_best.ncd.html
I get the following error message:
Error {
code = 500;
message = "Variable name (zeta) must be unique within Group ";
};
This corresponds with the following error message in my threddsServlet.log:

I'm not sure that this corresponds, but I also see this sometimes in my
catalina.out log file:
FMRC RAGGED HERE 61 != 60
The TDS catalog for this dataset can be inspected here:
http://oos.soest.hawaii.edu/thredds/catalog/hioos/roms_forec/catalog.xml
I have tried various things without success. Any ideas?? Thanks!
Cheers,
John Maurer
