Re: java.lang.OutOfMemoryError

Look at the docs for NSAutoreleasePool.  Wrap the inside of your loops in an 
autorelease pool to clean up the temporary objects that you create.  You will 
need to retain any objects created in the loop that need to live after it.

e.g.
for(j=0;j<BLOQUES;j++){
     // create pool
     // processing here...
     // release pool
}
