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 [ 104.383352] Killed process 2518 (oom03) total-vm:3152196kB, anon-rss:1048444kB, file-rss:192kB [ 107.946908] oom03 invoked oom-killer: gfp_mask=0xd0, order=0, oom_score_adj=0 [ 107.946912] oom03 cpuset=/ mems_allowed=0 [ 107.946915] CPU: 0 PID: 2521 Comm: oom03 Not tainted 3.14.0-rc8-1-iniza-small #1 [ 107.946917] Hardware name: SAMSUNG ELECTRONICS CO., LTD. 530U3BI/530U4BI/530U4BH/530U3BI/530U4BI/530U4BH, BIOS 13XK 03/28/2013 [ 107.946919] ffff880108e58400 ffff880064125be8 ffffffff8170fb45 0000000000000007 [ 107.946923] ffff880108e7a190 ffff880064125c68 ffffffff8170c6e5 ffff880064125cd8 [ 107.946925] ffff88010b686858 ffff88011fdf9d80 ffff88010b6863d0 0000000000000000 [ 107.946928] Call Trace: [ 107.946934] [<ffffffff8170fb45>] dump_stack+0x46/0x58 [ 107.946937] [<ffffffff8170c6e5>] dump_header+0x7e/0x1c3 [ 107.946942] [<ffffffff813881e0>] ? ___ratelimit+0xa0/0x120 [ 107.946946] [<ffffffff811580e4>] oom_kill_process+0x214/0x370 [ 107.946949] [<ffffffff81075ce5>] ? has_ns_capability_noaudit+0x15/0x20 ...
