Public bug reported: As far as I know, I don't have deja-dup set up to do anything.
Behavior: While using other applications, the system became nearly unusable, with inputs ignored or heavily lagging. The CPU fan was periodically cycling into high RPM. I could not even open another TTY. Eventually, GUI authentication messages started showing up asking for authorization to modify my user data. After much patience, I was able to open a System Monitor GUI and see that deja-dup-monitor was using over 10GB of RAM (out of 12GB on the machine). Killing this task ended the issue. Syslog shows a number of dconf-related messages about permissions denied while trying to create file /run/user/1000/dconf/user . This affected many applications, and some of them were condensed into "message repeats X times". In the case of deja-dup-monitor, however, the message repeated thousands of times.
