FortiSwitch FS-108F got CPU_SENSOR warning event and Memory high usage and System high temperature.

[jackylee0908]

Hi sir,

I got issues on my new FortiSwitch FS-108F which bought on two days ago.

In switch idle and standalone mode, and without any other Fortinet product connected to it:

1. There are several events about CPU_SENSOR reached/exceeded the threshold value, is it related to HW issue?

2. In the idle mode, no idea why the memory always over 60% utilization, and the system temp around 39~40 degree C.

I am considering to return this device back to seller and request refund, but before that, I'd confirm if the device has problem to use.

BTW, I have also export the debug report and sent it to Fortinet customer support for above issues.

Thanks,

Jacky

Hi Jacky,

Disable dhcp-snooping if enabled on vlans. If you still see issue then provide the following logs in the TAC ticket with FSW serial no.

show full-configuration

diagnose switch pdu-counters list
diagnose debug crashlog read
diag debug report

I am experiencing the same behaviour. Did you find a solution to this Problem? In my case the Switch is managed by an FG HA Cluster. The switch runs at 9% CPU usage and then every now and then reaches >87% and loses its connection to the management. After a while it comes back online and cpu goes down again.
