OT: 7609S Feature Manager and WCCP

Dear all,

sorry for posting an OT.

I've faced an issue on 7609-S router, which its engine is RSP720-3C-GE .
On one of the RSP's Gigabit interfaces, we *had "*wccp redirect in"
configured. After a topology redesign, we removed all wccp configurations
on the router, and configured PBR on the same interface.
The PBR has 4 sequences, each one of the first 3 sequences is matching a
different ACL (each has 3 ACEs referring to /24 subnets) and sets the
"ip *default
*next-hop" of the traffic to different next-hops than the default route,
and the last sequence permits all other traffic.
After removing all wccp configurations and implementing PBR, the CPU usage
of the RP (interrupt) has increased to 80% . When the PBR is removed, it
decreases to 1% .
The input traffic on the interface is just about 150Mbps, and the output is
around 300Mbps.

I went through lots of documents, and reached to Feature Manager.
Surprisingly, when I issue "sh fm wccp inband" and other related commands,
I still see the WCCP is the feature which bumps the interface.

HT-CoreRT#sh fm wccp inband
Current Slot Mask is 20
        Cache-Engine address: aaaa.bbbb.cccc at H/W adjacency:
                Slot 5: 524290
        Cache-Engine address: aaaa.bbbb.cccc at H/W adjacency:
                Slot 5: 524291
        Cache-Engine address: 192.168.64.6 at H/W adjacency:
                Slot 5: 524292
        Cache-Engine address: 192.168.64.6 at H/W adjacency:
                Slot 5: 524293
        Cache-Engine address: 192.168.64.6 at H/W adjacency:
                Slot 5: 524294
        Cache-Engine address: aaaa.bbbb.cccc at H/W adjacency:
                Slot 5: 524295

I've cleared the hardware logic of the interface, cleared all fm related
things, cleared CEF, enabled and re-enabled WCCP and PBR, and etc.
The last resort of solution would be reload, but I wish not to.

Hope you can help me.

Regards,
Mohammad
