Re: THREDDS and OPeNDAP



Hi James and Roy, 

Thanks for the information about the server.  I'll definitely post if I
find anything interesting with the tests :)

I do have one more question (although, I won't promise this will be my
last!)  I'm configuring the TDS to point to a directory for list all
*.nc files.  It works really well for most directories, but some just
fails with an "internal server error".   Could it be because those
directories have too many files? I'm currently using the datascan
element in catalog.xml to include .nc files.  It worked fine for a
directory containing 1500~ files, but failed for directories with over
3500 files.  Has anyone else ran into this problem?

When I try to load the directory, I get the following error:

--------------------------------------------------------------------------
Catalog
http://ngdev.sf.utas.edu.au:8080/thredds/catalog/argo_csiro/catalog.xml
has fatal errors:

Internal Server Error

I looked in catalina.out but no error messages were shown, and when I
look at threddsServlet.log, the following messages were printed out:

-----------------------------------------------------------

Finally, my catalog.xml file

....
<datasetScan name="argo_csiro" ID="argo_csiro" path="argo_csiro"
location="/library/argo_csiro">
    <metadata inherited="true">
        <serviceName>multiple</serviceName>
        <authority>something something</authority>
         <dataType>Grid</dataType>
        <dataFormat>NetCDF</dataFormat>
    </metadata>
     <filter>
      <include wildcard="*.nc"/>
    </filter>
  </datasetScan>
....

Let me know if you need anything else to help with diagnosing the
problem.

Thanks,

-Pauline.
