[netCDF #DRS-865582]: NetCDF: HDF error



Thank you for reporting this.  We've recently received a couple of reports 
related to netcdf-parallel.  While I can't offer any additional guidance at the 
moment, we will be looking to correct any issues that arise, which may also be 
responsible for the issue you've reported.

Thank you, have a good day,
