Hi, Request to elaborate the symptoms a bit more, like slow response in app behavior, etc, time pattern for slow response etc. Also, is it 4000 or 4000-M router?
11.2(16) itself is a very old IOS and obvious reasons for it being buggy, you may wish to upgrade the IOS basis the available memory. You would need a valid CCO account for this.

Hi..Thanks for the immediate response.
This is :
IOS (tm) 4000 Software (C4000-J-M), Version 11.2(16), RELEASE SOFTWARE (fc1)
slow response in terms of CPU utilization:
CPU utilization for five seconds: 48%/25%; one minute: 43%; five minutes: 44%
sometimes it goes very high around 90%.
Please tell me what is CCO account,is it the registered customer of Cisco who have purchased the cisco products from cisco .
Thanks again.
