Dashboard/WebGUI slows, hangs, and finally browser window crashes

[brainhig]

The dashboard & WebGUI become unresponsive and unusable after a short amount of time. Seems worse in Chrome than Firefox. This is an upgraded instance, mostly unconfigured, not being used except for testing.

Yup this has been happening to me after they did the UI overhaul.  I can only refresh the page, assuming it doesn't hang, to get everything back.

Can you pinpoint the widget that causes this? You can delete all of them, and add them one by one, and find out which one causes your issues.

Surely... I will begin testing those right away. I'll let you know what I find!

I believe it's the traffic graph.  Thats what I see crash out most and first.

It is the firewall graph that hangs the page for me. I had the traffic graph, cpu, memory, temp, interfaces and system information running for a day. After adding in the firewall graph, the page was unresponsive after 10 minutes in Chrome.

I was unable to upgrade from 25.1 as within a few minutes/ within an hour of upgrading (or full install from image) the GUI would bug out / crash often followed by a total unresponsive crash / freeze. I tried multiple installs with the same result and was able to reinstall 25.1 and run again with no issues.

After trying various things unsuccessfully I have done a full 25.7 reinstall and disabled the "Traffic graph" on the Dashboard - my router now been running fine for 20 hours. I still have the CPU graph running on the Dashboard.

Still early to say conclusively, but evidence suggests that in my case the Traffic graph was causing system crashes, no idea why.

My OPNsense box is : CWWK Intel N305, Alder lake i3

I have similar issues where the WebGUI will hang for a bit and eventually load the page.  It can happen at any time.

This is still an issue with the latest build. I'm just seeing this so I'll do some investigating however I can say that this is cross-platform as Firefox (140.6.0esr) for Linux (Debian 12) has the same issues. I run a pretty "busy" dashboard for five different OPNsense firewalls all running the latest open source version (OPNsense 25.7.10-amd64 : FreeBSD 14.3-RELEASE-p7 : OpenSSL 3.0.18) with only one of them crashing. That instance has only one dashboard widget different than the others, and that is the Certificates widget. Absolutely not sure if any of this will help, but if someone has something to try I can easily be a lab rat.

I experience the same with the Chrome Browser on my MacBook. With Safari I have no issues.
I deleted all widgets and start rebuilding when I recognized that Chrome will hang up also when I move the widgets.

At the moment Chrome is not usable with the new WebUi.
