Garageband System Overload

Hi all,

I have 16 GB of RAM

and almost all of my internal storage available. My MacBook has only been lightly used for music creation and really that's it. Yet, when on perhaps my 8th plus track on GarageBand I start to crash and get this "System Overload. The audio engine was unable to process all of the required data in time."

I can't possibly be crashing this often with this beef of a MacBook. I clearly have all of the required stuff to run the program, but it isn't optimal. Something has to be triggering this problem. Thank you all for you help and feedback.
