Matthew,

I can't recommend anything out of the blue. You may add 250 each time
to see when it goes away. Apparently, the consequence of using a
larger number would drive up memory usage. There is no other effect on
the computation.

You probably have a system whose packing is different from proteins.
It could also be due to the presence of many atoms with large radii.

All the best,
Ray
