I am training a fairly large dataset on Colab Pro+ with background execution. While the cell is running, the status reads 'busy' and I can check from the Resources tab that the notebook is indeed consuming RAM and disk memory. To check that the notebook continues to run, I close and then reopen it and check that the 'busy' status is still shown, or at least this is how I think background execution should work. Unfortunately, when I reopened the notebook after two hours, the status no longer shows 'busy'. Instead, it shows the RAM and Disk horizontal bars with a green checkmark to its left. The Resources tab shows that all consumption of RAM and Disk are flat.
Did my runtime restart and is there a way to prevent this from happening again?
