Traffic exceeds link capacity.

We have router which connected 45m hssi(A) with FR switch.
That router contains two other interfaces, one is 45m hssi(B) and the
other is 100m fddi (C).
Because the most of the inbound traffic from (B) and (C) goes to
(A) interface, the toal inbound traffic of (B) and (C) cannot exceed
45m. (Is it right ?)
But the output rate of interface (A) exceeds 45m, -I can verify them
in "sh int <int-name>"-, it increases upto 60~70 mbps. (Not really,
but the statistic from CISCO commands.)
When the phenomenen occurs, the total inbound traffic of (B) and (C)
shows near 45 mbps (about 43.x mbps).
My question is:
Is it true that it indicates 60~70 mbps ? (Of cause, it has many
output drops.) or Is it bug?
The cpu load increases upto 99%, and it freezes router for short
time -about 1~2 minute-. How to resolve this errors ?
Our Router is:
IOS: 11.1.19 (CC)
Enable CEF on (A): It is better than not using CEF. But the result
doen't matter. (High CPU load, ..)
Any Idea ?
Thanks in advance
