Is there additional detail you can provide here that might assist someone who uses MCNP to help you with this?

That happens when the cell description is too long. MCNP has a limit on that. Correcting this depends entirely on your problem geometry. If you can, break that cell into simpler Boolean expressions or different simpler cells.
