Comment 2 for bug 1894369

I have this issue too. It causes systemd's PID 1 (`/sbin/init splash` in htop) to use 100% CPU, which seems unfortunate.

When it happens, the log is filled with a whole lot of lines like this:

Sep 11 10:00:02 ubun systemd[1]: apport-autoreport.service: Start request repeated too quickly.
Sep 11 10:00:02 ubun systemd[1]: apport-autoreport.service: Failed with result 'start-limit-hit'.

Sep 11 10:00:02 ubun systemd[1]: Failed to start Process error reports when automatic reporting is enabled.

Followed by logs like this:
