Can Application Sensor cause high CPU usage on Fortigate 60D?

Please go to the CLI (Widget on the Dashboard or via SSH) and use the following command:

diag sys top 5 5

You can see which process causes high CPU/RAM Usage

Hi

Found the same in 800C on the ips version .

upgarded to 3.00079 fixed the issue . 800c is large enterprise box but still have 99.9 % of cpu when application monitoring is enabled and back to normal when disabled . Session rate 120-150 session per sec

ips upgrade fixed the issue

recommended ips version  3.00079

thanks

Hi All,

We have a Fortigate 60D and have been asked by our service provider to turn off the Application Sensor as it causes high CPU usage on the device resulting in policies not working well or internet being slow. May you let me know if this is the case as we would like to have it on so as to stop users abusing our bandwidth.

Your advice is greatly appreciated.
