Perhaps your computation required more space than was available in the Lisp system that was running your version of Maxima. You might, for example, run out of "string" space on some Lisp systems, without totally using up all storage.
Since you do not give enough information to reproduce your problem in Maxima (nor do you even address the issue of which version of Maxima you are using) it is pretty hard to help from the Maxima perspective. If you want help in Maxima, I suggest you construct a file of Maxima commands that will do your computation, and run it in Maxima (perhaps a better version than the one packaged with Sage) and see what happens.
