Title: Abnormally high CPU usage on web UI on OPNsense 25.1.9_2-amd64
Post by: brianbaggs@hotmail.com on June 26, 2025, 07:27:40 PM
Hello,

I have been using OPNsense for a little over a year now. I am using a mini-PC that is made for the purpose of being a router. It has 4 Intel I226-V ethernet ports, an Intel N100 CPU, 16GB of DDR5 ram, and a 512GB NVMe SSD. For the first year or so everything ran great and I was very happy with it, but ever since upgrading a few months ago, I am having an issue with the web UI.

Anytime I log into the web UI, the CPU utilization maxes out at 100% and stays there. As long as I'm not on the web UI, everything works great, but as soon as I login to the web UI, the CPU just starts maxing out. I ran top and saw that the problem was coming from php and php-cgi.

So I am wondering if anyone else has had a similar issue and was able to fix it? If so, I'd really appreciate it if anyone can share a way to remediate this issue. I checked the logs and I'm not seeing any errors or anything. Re-installing OPNsense is my last resort because I don't really want to do that.

Thank you.
