[SFOS v17.5 and v.18EAP1] High CPU consumption with minimal network usage. Any idea?

darnoK

Hi, could I ask you for help? I miss the idea.

In my home box (SG115 rev.2 with SFOS Home on board) have had high CPU usage since some SFOS update. After the upgrade to V.18, the problem continues, so it's definitely not a new firmware issue.

Do you have any idea why the CPU consumption with minimal network usage is so high? How can I diagnose a problem?

I will be grateful for any valuable hint.

PS I have several firewall rules for different devices (at the same time i have connected max. 5 telephones and 4 computers.), a mail rule and I use two physical LAN interfaces for two subnets.

best regards for Team

    Hi,
    I do not mean the orange icon, only the high processor rate. I think that the continuous spread between 40-90% is too much for the load I generate in normal use.

    After running the console> 'system diagnostics utilities process-monitor' command, I see high values ​​for 'snort' and 'apiInterface' (for both over 20-35%). It should be? Is this a good sign?

    It's interesting, because I connected the same devices to the FortiGate-60D with a very similar configuration and there the processor did not jump above 15%.
