Following up with a bit more info.
This dataset:
http://cida.usgs.gov/thredds/catalog.html?dataset=cida.usgs.gov/wicci/cmip3/20c3m
And this one:
http://cida.usgs.gov/thredds/catalog.html?dataset=cida.usgs.gov/wicci/cmip3/sres_early
Are identical except one is for a period in the future (sres_early) After some
period of time with no direct use of the dataset, the netCDFSubset page starts
to come back 500 for the sres_early. For the 20c3m, the netcdf subset page
comes back 200, but I get stack trace 1, included below.
A related DataBtree error can be reproduced by asking for the coordinate
variables of this dataset:
http://cida.usgs.gov/thredds/dodsC/stageiv/stageiv_archive.ncml.ascii?lon[0:1:1120][0:1:880]
The threddsservlet log stack trace is included as stack trace 2 below.
What’s odd is that the server works as expected for some period of time or
volume of usage then goes into this state where some aggregations of netcdf4
data produce DataBTree errors and some NetCDF Subset pages return 500 with
nothing in the logs indicating a failure. In fact, for the NetCDF Subset 500
errors, there is no ‘Request Completed’ in the threddsservlet log.
This is only happening with some datasets and it appears that the core datasets
we host are all functioning as expected. I’d really rather not roll back to an
old version if we can identify a fix for this. If I need to take the time to
provide sample files I can do that, but I’d need to know specifically what is
needed to look at it more closely.
Thanks!
