Memory grows using parallel

Hi, It's my first approach to the parallel computing, and I wrote a matlab code to take advantage this feature in Matlab. My problem is that the memory usage during the parallel run (using a parfor call) grows until I get an out of memory error.
My code is something like:
DATA=rand(1000,1000);
for k=1:1000
A=DATA(k,:);
B=DATA(k,:);
parfor i=1:100 do_something; end
end
I tried to clear out all the unused variables and pass to the function inside the parfor only the necessary part of data to ensure the smallest overhead, but it seems that in some way the code occupy even more memory for each run. Furthermore the whos output during each run didn't reveal the puzzle (all the variables have the same size).
Any ideas/suggestions to help me solve the problem?
Regards d
