I am solving a complicated motion of equation using NDSolve, and when I do it, I get following error message.

NDSolve::"ndsz": "At t == 0.12675818270208772`, step size is effectively zero; singularity suspected."

So the solution is in "step size", and what I like to know is what is the default value of "StartingStepSize". The book only states as "Automatic", but no mention of numerical value. I figure that changing the StartingStepSize might solve the problem, however, if anyone has better idea, feel free to let me know. I'd be very appreciated.
