Do a: sh cam-partition detail
See if any of the cam counters are (near) zero, if so you might need to
restructure your cam partitions. When running out of CAM, the packets
will be processed over CPU, something you really don't want to do on a
bigiron.

There are totally no IP ROUTING. Only MCAST ROUTING and L2 switching.
Now I have added no icmp redirects. but as far as here are no IP
routing traffic, there are no icmp redirect generates and no any CPU
changes seen. Also I already have
no ip source-route
in the config
There are no RIP, no OSPF. only MBGP routing protocol.
# egrep '^router' config
router dvmrp
router pim
router msdp
router pim
router bgp
in bgp router no any unicast active neighbors. only for address-family
ipv4 multicast
we already have
ip multicast-perf
in our config for at list last year. (switch was rebooted after this
command added)
Same as we already added
mcast-hw-replic-oar
ip multicast hardware-drop
in config and it was reboted after such commands added. No any changes
seen.
Also I tried to add
router pim
+ hardware-drop
and no any changes seen.

always use "no ip icmp redirect" !!!
this safe Your CPU :)
I dont sure Your multicast problem is this, but just use it. This
reflect to OLD RIPv1 based routing only, I sure you dont use rip.
try use "ip multicast-perf" too / need reload btw to see changes /
sorry for my bad english
