Cannot execute matlabpool close on the labs.

Hi:
I'm just starting doing parallel programing and till now everything went fine, but now I get an error I don't understand.
*Error using ==> parallel_function at 598 Error in ==> matlabpool at 135 Cannot execute matlabpool close on the labs.
Error in ==> getallbiggervecs at 43 parfor i=1:m
Error in ==> getallbiggervecs at 36 y=[y;getallbiggervecs(Y,Xvar,nucleos)];
*
It's just my intuition, but I think that parallelism doesn't work fine with recursive functions.
Here's the routine (I added an extra if to use normal for.loop and compare):

You can nest a PARFOR loop invoke another PARFOR loop, but you will not get any additional parallelism. (due to a current limitation, the inner PARFOR loop cannot occur directly in the text of the outer PARFOR loop) There is no extra parallelism because you cannot open or close another MATLABPOOL on the workers. (One way to tell if you're on a worker is to ask "isempty(getCurrentJob)")
