Answer 1

Use Eclipse, PyDev, PyCharm, or whatever to set a breakpoint at the misbehaving line of code and step through your code from there. Tornado applications are relatively difficult to debug because the stack trace is less clear than in multithreaded code. Step through your code carefully. If you use coroutines, you should become familiar with the implementation of gen.Runner so you can understand what your code does during a "yield".
