The Digital Earth Africa Sandbox has a finite amount of processing power allocated to each user. This means if you attempt to load or calculate a lot of data, the kernel may crash. You will see a message like this:

You will not lose any files, but will have to rerun your notebook to continue working. However, if the notebook is still demanding too many resources, it will crash again.

You can prevent kernel crashes by:

• Decreasing the area selected for data processing

• Shortening the time extent

• Shutting down kernels of notebooks you have finished using: open the notebook and select Kernel -> Shut Down Kernel

These actions reduce the memory load of your computation on the Sandbox.
