This error occurs when a single node has too much data. The problem usually results from a node's data being copied as conditioning arrows are added to it.
A value node which has ten blue arrows leading into it from three state discrete chance nodes will have over a thousand formulas, even though they may all be the same. If another blue arrow from a three state chance node is added, the number of formulas will triple.
To solve this problem, use black arrows when the dependent node doesn't need to have a different formula for each state of the conditioning event.
