I'm running Ubuntu 20.10. But I think I can answer my own question. It just happened again, and this time all I needed to run was run `apt update`. I didn't even install anything! A quick google search found this page: https://www.linuxuprising.com/2020/07/how-to-restart-gnome-shell-from- command.html. I pressed Alt-F2 and then r, and that stopped the logging without a reboot!
I'd still like to know why this suddenly keeps happening. 21.04 is due out in a few weeks and I'm hoping that will fix it. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1905519 Title: Syslog is flooded with Object St.Bin (0x565425162c80), has been already deallocated — impossible to set any property on it.
