Note that there are not really any 10-12 bond terms, in all probability.
Amber uses this notation for atom pairs with no nonbonded interactions
(of any sort, 10-12 or 6-12).

You might be able to get away with reducing your skinnb to a small value.
Otherwise, you need to make a bigger system...Amber is not set up to handle
very small unit cells (of the order of the cutoff).

...good luck..dac
