Flushes on a fastethernet interface

Question

Hello,
I've got a problem with a fastethernet on a 7206 VXR router. On the show int of the affected interface, you can see the drops and flushes I'm getting:
Input queue: 0/200/14/4199 (size/max/drops/flushes); Total output drops: 0
As you can see, I have increased the input buffer from the default of 75 to 200. Flushes and drops are still increasing. I have also changed to fast switching on the interface but I am still getting the same issues. This doesn't seem to be service impacting, I would just like to get to the bottom of the issue and see if it can be rectified. If anyone could offer any advice, it would be much appreciated. Many thanks.

Hi Guys, many thanks for your responses. I've used the sh inter fas 0/0 switching command and got the following:
#sh interfaces fastEthernet 0/0 switching
FastEthernet0/0
Throttle count 60
Drops RP 72 SP 0
SPD Flushes Fast 10105 SSE 0
SPD Aggress Fast 0
SPD Priority Inputs 103921 Drops 0
Protocol Path Pkts In Chars In Pkts Out Chars Out

The bit i'm interested in is the drops RP 72. What is RP, I can only think of Rendevous point for multicast, but we aren't running multicast on the router!! Any help greatly appreciated. Many tks.
