Error here, error there. The problem finally is that we got an order (entered by client) for over 600 Billion units to be put on a single truck. Now admittedly the units are small, there fit about 100.000 units on a pallet.. But that is still an aufull lot of pallets to fit. The error is only noticed because each pallet needs a label and people expected just 10 labels but the printer didn't stop after 10. So our programs must be in error.
