I'm happy I found this thread as I'm suffering from the exact same problem on my private opnsense router.
The WebGUI is quite unreliable, the dashboard loads widgets only seldomly (oftentimes after a fresh restart) and my uptime shows the exact same weird value of 20611 days. Also other parts of the WebGUI, like for example the DHCP leases overview, often don't show information. A few page reloads later it might. System updates via the WebGUI don't work as well. Via SSH everything is fine.
Just to make things clear, system time seems to be fine.
top doesn't show high load, but I'm wandering why this machine swaps with 8GB of RAM.
I'm pretty sure it has to do with my configuration or something going havoc on the network. Any business opnsense installation i came across doesn't show this behaviour. But I ran out of ideas how to identify these problems? Any suggestions what to look for or which logs might be helpful?
