The best approach is to start small, and work your way up to a big 
problem like that if necessary. Start by aborting the calculation and 
then start testing much smaller examples.

Some Mathematica functions - such as Simplify or FullSymplify - seem to 
get stuck in this sort of way - if they do that, they will hang for ever.
