Hi everybody,
I'm working on a CISCO 2821 voice gateway, the IOS version is 15.1(4)M5, RELEASE SOFTWARE (fc1).
The problem is that the command "show processes cpu" shows huge percentage (93%)
sintcvo01#sh proc cpu sorted | ex 0.0
CPU utilization for five seconds: 92%/9%; one minute: 93%; five minutes: 93%

Hi Amin,
Try disbaling SNMP logging/trap ,as you can see SNMP is taking a toll on CPU.
You can probably try a reboot after that,should fix it.thanks

Indeed, I the thing now is that a big portion of the CPU resources is taken by hidden processes.
how to gain back this big portion of CPU?
Thanks in advance, Deepak.

You can raise a TAC case for CPU profiling of your router which can give you exact details around the CPU processes cuasing this.
Refer to below doc.
