I sometimes use a variant of rubber duck debugging. Two projects I have been responsible for started by me taking over from a contractor who was on-call to resolve issues. I would start an email to him describing the problems and asking good questions. More often as my understanding of the systems progressed the emails would not get sent since the act of explaining it to someone I knew could fix the problem led me to understand the error.
