Bryan Pendleton commented on DERBY-3842:
----------------------------------------

I agree. I think we wanted to see sort type 'external' here.

It looks like the code that handles derby.storage.sortBufferMax is around
line 210 of org.apache.derby.impl.store.access.sort.ExternalSortFactory:

        else
        {
            // if user specified derby.storage.sortBufferMax, use it.
                sortBufferMax = defaultSortBufferMax;
        }

Maybe you can investigate whether this code is actually seeing the value
of sortBufferMax = 5?
