High CPU and slowness even when not downloading

[gnomehole]

In the past couple weeks I've found Sabnzbd is crashing on my Mac. If I load it, I can't even click on settings without it spinning the browser (doesn't matter which browser) and taking forever. If I'm lucky, it will load settings... otherwise it sits around 120% CPU then says "lost connection"

When it downloads, I can see it processing by watching the incomplete folder but it won't let me see the status screen in the browser.

Things have been stable for a long time. I've tried going back to 2.3.4 but that doesn't change anything. Nothing else has really changed in my environment that I know of, this system is usually rock solid.

I am seeing this in the logs:

Any suggestions?

Cherrypy is the webserver framework in SABnzbd, so if that says "error: [Errno 24] Too many open files", there is something strange going on between SAB and your webbrowser or other clients accessing SABnzbd.

So ... if your star SAB, and no webbrowser, what is the CPU load?
And what if you use another webbrowser?

Thanks for the tip that it might be a client. Ultimately found NZB Control running on my personal Mac may have been the cause.

I also restarted Radarr and Sonarr at the same time so one of those three must have been doing something.
