Hi
    I have been checking a switch for high CPU Util, below is the output of the processes.  I added bpduguard to all the access ports which were missing looked like a BPDU flood,  this did not fix the issue.  It is a Cisco C2960. Any ideas guys on the fix.  I rebooted the switch it cleared the process, is there anything else I can do other than rebooting the switch in the furure ?

CPU utilization for five seconds: 90%/0%; one minute: 88%; five minutes: 85%
