Your description is extremely vague to say the least. Do you an insert trigger on Table1 that inserts data into Table2? And you also have an insert trigger on Table2 that inserts into Table1? That is what I think you are saying. This is one of the reasons to try to avoid triggers if at all possible. You can't get out of that loop. You need to come up with a different way of doing whatever these triggers are trying to do.
