There is abnormal usage of CPU on the new core switch 4507, the details as below, anyone who can help me ?
I found the process "iosd" occupies around half hundred percent of CPU usage.
Core_WS-C4507#sh proc cpu sorted
Core 0: CPU utilization for five seconds: 8%; one minute: 12%; five minutes: 39%
Core 1: CPU utilization for five seconds: 98%; one minute: 93%; five minutes: 66%
PID Runtime(ms) Invoked uSecs 5Sec 1Min 5Min TTY Process
