I Have Debug Port turned onto Serial, and Level turned to All. I push the code to the ESP, and after a random period of time (under 10 minutes normally), I get this.

I have two questions please:
1) What causes such a crash. I have tried many different power sources and serial connection combinations. This is just simple code, but when I have my more complex code, it can crash and reboot, or it can crash and hang. At the end of the day, the reboot does not bother me, its the crash and hang that is annoying.
2) How is it connecting to MyWiFi (which is my AP), without any code to make the connection? I can even ping it.
