Do you get a stack dump? If so, that means the controller has crashed and the stack dump is supposed to provide debugging information.
On a possibly related note, I have finally figured out the weird recycle loop issue with some OpenGarage units. Turns out this issue has been reported previously:
https://github.com/esp8266/Arduino/issues/1054
and the fix is simply adding a line of code at the beginning of the setup function. For details, check my blog post:
