<HaltServer 'Worker failed to boot.' 3> - Heroku Crash --- Worker failed to boot

Question

Every now and then with my Django project launched on Heroku, it crashes. I know it is a change I am making somewhere but I cannot figure out what I am doing that is causing it. It's not completely random but I set DEBUG = True and turned off collectstatic and it crashed. I don't know if it is totally that or something else that I am doing but I just want to educate myself on it. I'm posting the Heroku log tails below. It is what I have been trying to decipher for a while now. Can anyone help me find out why my Heroku app keeps crashing?
