    Hello, 

    I have  a stack of  4 -2920 switches ring topology and the CPU constantly runs above 70%. 

     

    Task usage for last 9 seconds
    % CPU | Description
    -------+--------------------------
    25.7 | Idle
    4.4 | Sessions & I/O
    0.8 | Hardware Mgmt
    68.1 | System Services
    0.3 | HTTP
    0.8 | TFTP

    I was looking to find out what funtion is the  System Services process and is this normal behavior. My other stack of 4 2920 same setup up are not experiancing this behavior. The software version is WB16.04.008 also viewing the process tracker System Services-36 is consuming 66 %

     

    Any feedback would be helpful. 

     

    Thanks!
