This is definitely the problem. You might have been at the edge of 1 dataset and now your SMF is on two datasets. As a general rule the use of prm=smfdump should have DISP=MOD. Fix this and get on with your life. Don't worry about why this just started to happen because the disp was wrong to begin with.
