Ian Johnson (anonymouse67) wrote : apparmor fails to start with no parser errors

On Ubuntu 18.04.2 LTS Desktop, after running out of space on my disk, my system was unable to finish booting and I had to go into recovery mode and remove a number of files before the system would boot. After doing so I discovered that now the apparmor.service systemd unit always fails to start. I see this in dmesg:

[ 1066.975360] Out of memory: Kill process 6799 (apparmor_parser) score 796 or sacrifice child
[ 1066.975364] Killed process 6799 (apparmor_parser) total-vm:15057348kB, anon-rss:15046148kB, file-rss:0kB, shmem-rss:0kB
[ 1067.406595] oom_reaper: reaped process 6799 (apparmor_parser), now anon-rss:0kB, file-rss:0kB, shmem-rss:0kB

Whenever apparmor.service is attempted to be started by systemd, i.e. either on boot, or later with `systemctl start apparmor`.

The log from journalctl doesn't show any actual issues with any profiles just this:

I can see that apparmor profiles are active after doing this (using aa-status), but it's still troubling that apparmor runs into an issue without actually saying what the error is.
