Or alternatively you can try to set sleep between openings.

To clarify, do you mean adding a sleep of e.g. 1 second prior to your preprocess function (and setting preprocess to just sleep then return ds if you're not doing any preprocessing)? Or, are you instead sleeping before the entire open_mfdataset call?

Is this solution only addressing the issue of opening the same ds multiple times within a python process, or would it also address multiple processes opening the same ds?
