High CPU Usage on C1921/K9

Hi All,

    I met a problem with my C1921/K9 router. CPU usage on it is constantly 90%.

    When I used "show process cpu sorted", I found the process called "Switch Link Moni" occupied 75% of CPU resources.

    I have tried searching what the process is used for for a really long time, but I couldn't find any document about it.

    Result of "show process cpu sorted" is as below. Could any expert help me to solve the problem ?

 

    CPU utilization for five seconds: 89%/15%; one minute: 89%; five minutes: 89%
