High CPU usage on CPU management unit

Hello,

I have a DELL MXL switch, which is showing a high CPU usage on management unit. It shows two processes consuming 92% of utilization. The processes are , "system" and "sysdlp".

NETM17>show processes cpu management-unit 10

CPU utilization for five seconds: 91%/2%; one minute: 92%; five minutes: 92%
PID        Runtime(ms)     Invoked       uSecs     5Sec    1Min     5Min TTY           Process
0x00000000   540192750    54019275       10000   54.35%  55.76%   54.90%   0            system
0x000001f9  1464180500   146418050       10000   36.76%  37.31%   38.04%   0            sysdlp

How can I troubleshoot this issue?

Thank you in advance.

Best regards.

Ruben Garcia.

Hi,

Is there a lot of traffic on the switch? Are there a lot of ACLs? Is the firmware up to date? It may be working fine if there is a lot of traffic or rules that cause high usage.
