25.10 Web UI unresponsive after a day or so

Hey everyone. I recently upgraded to 25.10 (not realizing it was still “early adopter”), and I’ve been having a dog of a time with the web UI since. Everything will work fine after a reboot for a while, but then I eventually can’t hit the web UI.

It doesn’t seem like a networking issue (nothing has changed), and I can bring the web UI back with either a reboot or “service middlewared restart”, but surely this shouldn’t be happening with regularity, right? Any ideas?

I’m about to roll back the boot environment, but I had set up a couple containers after 25.10 (mainly PBS) and I gather those don’t carry back over?

Thanks.

I ran into a similar problem during 25.10 Beta, but it disappeared sometime later.

In my case the problem seemed to be nginx and a ‘systemctl restart nginx’ brought things back to life.

You might want to check the middlewared.log (/var/log/middlewared.log) for abnormalities. But from my personal experience it rather seems to be some regression in middlewared (aka asyncio_loop) itself, that leads to that process tree eating up more and more cpu resources. Using the GUI seem to contribute to this. Just search the forum for “asyncio” and you will probably find quite some people having the same problem. So for now restarting the middlewared service regularly is the only mitigation…
