"throttles" increased so fast in Fastethernet of 7204 VXR

There is 7204VXR(12.2.1) that connected to 6509. There is only two 2M leased line in 7204. When I pinged a lots of packets in working conditions. I found succeed rate is only about 95%. I found the "incoming drop" and "throttles" var increased very fast under FastEthernet interface. There is not any other error expcept this one.

The other side is 6509 100M port, so I don't think the traffic burst is big enough than the capability of 7204VXR.I think mabye it is software or hardware bug.Am I right?

The following is part of "show int fas 0/1":

Re: "throttles" increased so fast in Fastethernet of 7204 VXR

Can you check for the CPU load on the 7206?

From the documentation:

"Throttles are a better indication

of an overloaded router. They show

the number of times the receiver

on the port has been disabled,

possibly due to buffer or processor

overload"
