It will not help but thank you for your input.

60% of our daily load failed twice today. This is not an isolated incident. We are talking about 40-50 concurrent DataBricks notebooks, that worked fine just yesterday and in the last seven days.

We will open MS ticket tomorrow, but this is not looking good. I have to say that an incident of this scale is an eye opener for us and a big red flag going forward with DataBricks

Multiple cells report the same error as shown below:

Failure starting repl. Try detaching and re-attaching the notebook.
