Using:

  • xarray=0.16.0
  • dask=2.25.0
  • netcdf4=1.5.4

I am experiencing same when trying to write netcdf file using to_netcdf() on a files opened via xr.open_mfdataset with lock=None (which is default).

Then I tried to open files with lock=False and it worked like a charm. Issue have been gone for 100% of times.

BUT

Now I am facing different issue. Seems that hdf5 IS NOT thread safe, since I encounter NetCDF: HDF error while applying different function on a netcdf files which were previously processed by another functions with lock=False. Script just terminates not even reaching any calculation step in the code. seems like lock=False works opposite and file is in a corrupted mode?

This is the BIGGEST issue and needs resolve ASAP
