Yuanji,
I think you are bumping into limits on the size of the data that the TDS
will serve up. I was able to make a request for a subset of the times
in ascii, and they came through. Similarly, the request for all
temperatures and times as binary came through just fine. The limits are
set in threddsConfig.xml, and is described here as ascLimit and binLimit:
http://www.unidata.ucar.edu/projects/THREDDS/tech/tds4.3/reference/ThreddsConfigXMLFile.html#opendap
I noticed that the particular server you pointed me to is running an
outdated version of the TDS (4.2.10). We recommend that everyone
upgrade to our latest version (currently 4.3.16), as it is much easier
for us to provide support. For instance, the 4.3 server we have running
here would have returned the following error, instead of the 500 you saw:
Error {
code = 403;
message = "Request too big=24184.0 Mbytes, max=50.0";
};
Cheers,
Lansing

Hi,
We recently published one ncml file to the THREDDS server.
http://data.nodc.noaa.gov/thredds/dodsC/testdata/20130328/aggregate_BML_DOU_joinExisting.ncml.html
We are able to get the ASCII for the variable "temperature" with whole
time period, about 2290301 values.
It returns error if we try to get both "temperature" and "time" with
all the layers. The error message looks like
Error {
code = 500;
message = "readAgg
file:/sites/data.nodc/htdocs/testdata/20130328/aggregate_BML_DOU_joinExisting.ncml";
};
Could it be problem with the ncml aggregation of TDS?
Thanks a lot,
Li
