Recovered from a dead kernel in Jupyter

The best way to keep Jupyter within Data Scientist Workbench healthy is to stop any running notebooks after you're done with them.

Running notebooks are marked with a lightning bolt in the "Recent Notebooks" sidebar. To stop them, you can expand the twistie icon next to the notebook name and choose "Stop".

You can also go to "File" > "Close and Halt" within Jupyter if you still have the notebook open on your screen.

Once you've closed the other notebooks, you can restart your dead kernel by going to "Kernel" > "Restart" within Jupyter.
