It sounds like this is an issue that only comes up when using open_mfdataset? Is so, this indicating that the problem is likely somehow related to using dask arrays.

It be nice to have a minimal example of what goes wrong that doesn't require reading/writing netCDF files. Can you construct a synthetic dataset in memory that exhibits this problem? Note that you can use the .chunk() method to chunk arrays with dask.

Can you reproduce this with a synthetic dataset? Please read this guide on "Minimal Bug Reports": http://matthewrocklin.com/blog/work/2018/02/28/minimal-bug-reports
