Very easy - rowhash isn't an injective function.
The same phenomena may occur in Tpump, but in Tpump there is a remedy - serialization (DML statements with identical hash values of the rows
are submitted from the same session).
To solve it in Informatica you can use one session ( for small tables) or switch to multiload/fastload protocol.
