Since you're using object graphics, are you sure that you're destroying
all of your objects when appropriate? Simply forgetting an obj_destroy
on the end of a loop or subroutine will lead to all your memory getting
filled up. Also, note that reassigning a variable name does not destroy
the object.
a = obj_new('someobject')
a = obj_new('someobject') ; <-- memory leak!
a = obj_new('someobject')
obj_destroy, a
a = obj_new('someobject') ; <-- no memory leak now
Don't know if you have either of these cases in your program or not.
You can try doing a help, /heap and see how many objects and pointers
you have defined. If the list keeps growing and growing and growing
until memory is gone, I'd think a memory leak is the most likely culprit.
