There is a problem experienced in the Cisco Switch 3750, whereby the CPU usage is very high, sometimes reaching 100%.

When I do "show processes cpu sorted", it is shown that "HTTP CP" consumes the most CPU usage (around 85%).

Below is the output:

Switch#show processes cpu sorted
CPU utilization for five seconds: 100%/2%; one minute: 43%; five minutes: 20%

Can anyone advise the possible reasons for the high CPU usage in "HTTP CP" process?

Thanks.
