What happened?

I am reading the era5 nc data and extracting the values by latitude and longitude. My code worked fine for 8 hours but then suddenly it broke. Here is the error message. I'm guessing its an error related to the threads?

What did you expect to happen?

MVCE confirmation

• [ ] Minimal example — the example is as focused as reasonably possible to demonstrate the underlying issue in xarray.
• [ ] Complete example — the example is self-contained, including all data and the text of any traceback.
• [ ] Verifiable example — the example copy & pastes into an IPython prompt or Binder notebook, returning the result.
• [ ] New issue — a search of GitHub Issues suggests this is not a duplicate.

Anything else we need to know?

My code is not easily simplified so it may not be reproducible, the last time I ran the code it was an error after 5 hours of normal work. first: 53%|█████▎ | 952/1803 [5:32:09<4:56:55, 20.93s/it] second: 78%|███████▊ | 1408/1803 [8:02:31<2:15:22, 20.56s/it] The error is the same
