The part of the expression which is probably causing this: (MaxTransactionId + 1) / OLDSERXID_ENTRIESPERPAGE - 1
Which I fear may not be getting into overflow which will not do the
right thing even where there is no warning. :-(
Would it be safe to assume that integer division would do the right
thing if we drop both of the "off by one" adjustments and use?: MaxTransactionId / OLDSERXID_ENTRIESPERPAGE
