Sorry, but you've provided only part of messages and i can tell that the process was killed in /machine.slice/38104 cgroup (CT 38104) because of low kmem limit in that cgroup:

[ 79.125100] Task in /machine.slice/38104 killed as a result of limit of /machine.slice/38104
...
[ 79.125119] kmem: usage 17488kB, limit 17488kB, failcnt 49

Other issues may be caused by similar limits or it might be something else.

Anyway i'd start with reviewing logs, checking failcounters in messages like
[ 79.125119] kmem: usage 17488kB, limit 17488kB, failcnt 49

and getting rid of kmem limits at all for Containers.

kmem is accounted into total ram+swap, so no need to limit it independently.


If your problem is solved - please, report it!
It's even more important than reporting the problem itself...
