ARP Traffic High

hello,

i have a network setup with one Cisco core switch 4500 series, around 150 access switches that are connected to this single core switch, core switch forwards the traffic to the router 2921.

problem is that the router ARP traffic most of the time reaches 100% utilization and the users will not be able to do browsing, ping will work but there will be no browsing, if i restart the router, it will again start working... it happens around two times in a day..

what is the solution for this ? how can i prevent arp traffic reaching 100% ?

please suggest something.
