I've been trying to understand and/or fix a problem where occasional "HDF

It would be quite helpful if you would include the HDF eror -- it's
probably two screenfuls of nonsense but it might give an indication of
what went wrong.

The errors are sporadic (but
reproducible) and necessitate a lot of "try/catch" type of structures to
deal with the few values that are apparently corrupt. I've got to read
terabytes of many small netcdf files and performance has been a problem in
matlab, so I'm switching to fortran and hoping I can find out what the
problem is and fix the netcdf, if possible.
There is an old thread, referenced in my subject line, which mentions a
function
nf_set_log_level
but this symbol seems to be missing from my netcdf library. Since it is
undocumented, I wonder if anyone here can help.
Netcdf Information: (nc-config --all)
This netCDF 4.3.1.1 has been built with the following features:
--cc -> /usr/bin/clang
--cflags -> -I/opt/local/include -I/opt/local/include -DNDEBUG
--libs -> -L/opt/local/lib -lnetcdf
--has-c++ -> no
--cxx ->
--has-c++4 -> no
--cxx4 ->
--fc -> /opt/local/bin/gfortran-mp-4.8
--fflags -> -pipe -Os -I/opt/local/include
--flibs -> -L/opt/local/lib -lnetcdff -L/opt/local/lib
-Wl,-headerpad_max_install_names -lnetcdf -lnet\
cdf
--has-f90 -> yes
--has-dap -> yes
--has-nc2 -> yes
--has-nc4 -> yes
--has-hdf5 -> yes
--has-hdf4 -> no
--has-pnetcdf-> no
--prefix -> /opt/local
--includedir-> /opt/local/include
--version -> netCDF 4.3.1.1
NB: The many files I am working with are huge enough that I am utilizing the
netcdf compression feature, which I believe are available only in netcdf 4.
If not for this, I would downgrade to netcdf 3.
