netflow is showing speed higher then link speed

Hi

We are facing problem.Our netflow analyzer 6 shows speed higher then links speed. We have E1 (2Mbps) internet link.Interface is also configured on 2000000bps, but netflow some time shows speed 2.22Mbps, more then link speed.And if i get stats of one month, then it shows maximum speed 3.63Mbps.Which is impossible.Can anybody help me out what is the issue?
