I guess that you obtained this via the web interface demo.
The bare point is that the solver in the web interface has been tailored 
to only use a limited amount of both CPU time and system memory, so as 
to avoid our web server to become unresponsive: since the computation 
above requires more memory, a deliberate error condition is raised.
You can still solve the same recurrence using the web interface, 
provided you remove the initial conditions (and you do not ask for the 
verification of the solution).
