Hello everyone, I brewed up a partial mash Oatmeal stout. I'm not sure why, but it fermented violently for 3.5 days and produced a HUGE yeast cake after it all settled down:

Looks like I lost about a gallon of brew (the airlock is still bulbing couple times a minute). Does anyone know why this happened? or what I should/can do about it?
