CPU Load on a NG2100 with latest 24.03

s25a

Hi Everyone,

I setup a new SG2100. Just did some basic config like Time Setup and Ip-Adress. Also did the update to 24.03.
I saw a continous cpu load of about 20% - 30%. No packages are installed.

After inspecting Diagnositcs/System Activity it shows:

last pid: 42761;  load averages:  0.81,  0.81,  0.63  up 0+00:11:08    12:19:35

I did some research on the the php-fpm: pool nginx (php-fpm) and found some similar threads here but no Solution so far.
What is the right process to get this solved?

My assumption would be the cpu load should be max 1-2% without any packages installed and with no devices connected. (Except one PC to configure the firewall)

Thanks S

Hi, have you tried restarting pfSense?
I am on pfSense 2.7.2 and I saw this problem on some devices that I updated, so I did a reboot and the CPU and RAM consumption was reduced almost as much as before the update

Hi,

thanks - yes i restarted the device several times that should not be the issue.

@s25a Having the dashboard UI open on 1100 and 2100 does consume quite a lot of CPU (20%+ ish) depending on the widgets.
Please try and only SSH to your pfsense and see if the CPU usage remains so high without a open websession

Hi,

thank you very much. I tried and accessed via SSH. And yes the CPU load there is about 5%.
I did not expect that the GUI consumes that much but good to know - Thank you very much for the information

Have a good day
