I don't actually see any oopses there. There are some stack traces
associated with the oom-killing events:


[ 104.383349] Memory cgroup out of memory: Kill process 2518 (oom03) score 777 or sacrifice child

...

But these aren't oopses - mm/oom_kill.c:dump_header() deliberately
performs a dump_stack() while reporting on the event.
