Still doesn't seem right..

eg..

[42309.542776] [ pid ] uid tgid total_vm rss cpu oom_adj oom_score_adj name
..
[42309.553933] [ 500] 81 500 5435 1 4 -13 -900 dbus-daemon
..
[42309.597531] [ 9054] 1000 9054 528677 14540 3 0 0 trinity-child3
..

[42309.643057] Out of memory: Kill process 500 (dbus-daemon) score 511952 or sacrifice child
[42309.643620] Killed process 500 (dbus-daemon) total-vm:21740kB, anon-rss:0kB, file-rss:4kB

and a slew of similar 'wrong process' death spiral kills follows..
