High CPU Usage on J9727A 2920-24G-PoE+ Switch

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!
