I had the same problem of HDF5 DIAG warnings after upgrading to xarray v2023.3.0 yesterday. Your diagnosis in [SciTools/iris#5187](https://github.com/SciTools/iris/issues/5187) helped isolate the issue with libnetcdf v4.9.1. Downgrading libnetcdf to v4.8.1 resulted in no HDF5 warnings.","{""total_count"": 2, ""+1"": 2, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,1596115847

See our issues here : https://github.com/SciTools/iris/issues/5187
It does look a lot like the ""same"" problem.
It is specifically related to the use of dask and multi-threading.
Here in python-netCDF4 land, we were protected from all of that before netCDF4 v1.6.1, since before that all netcdf operations held the Python GIL so could not be re-entered by threads.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,1596115847
