      OP_REPLY in the MongoDB wire protocol includes a "startingFrom" field. It is defined as a signed 32 bit integer. That's unfortunate since a MongoDB collection can have a much larger number of documents. If you validate this field (like the python driver...) a user that iterates a large collection (more than 2147483647 documents) will receive an error when the server overflows the startingFrom value and returns a negative number.

      The consensus of opinion seems to be that validating this field isn't particularly useful. If your driver does validate, remove the validation.
