Public bug reported: Seems that there's a bug in kernel related to working with memory, especially to decide when to run oom-killer.
One morning I found my system frozen with he following in logs after reboot: May 12 07:51:41 big -- MARK -- May 12 08:00:37 big kernel: [233387.108621] type=1503 audit(1242100837.141:10): operation="capable" name="sys_admin" pid=11357 profile="/usr/sbin/cupsd" May 12 08:00:37 big kernel: [233387.108630] type=1503 audit(1242100837.141:11): operation="capable" name="sys_resource" pid=11357 profile="/usr/sbin/cupsd" May 12 08:00:37 big kernel: [233387.108636] type=1503 audit(1242100837.141:12): operation="capable" name="sys_rawio" pid=11357 profile="/usr/sbin/cupsd" May 12 08:00:37 big kernel: [233387.108652] type=1503 audit(1242100837.141:13): operation="capable" name="sys_admin" pid=11357 profile="/sbin/dhclient3" May 12 08:00:37 big kernel: [233387.108657] type=1503 audit(1242100837.141:14): operation="capable" name="sys_resource" pid=11357 profile="/sbin/dhclient3" May 12 08:00:37 big kernel: [233387.108663] type=1503 audit(1242100837.141:15): operation="capable" name="sys_rawio" pid=11357 profile="/sbin/dhclient3" May 12 08:00:37 big kernel: [233387.108843] rhythmbox invoked oom-killer: gfp_mask=0x1201d2, order=0, oomkilladj=0 May 12 08:00:37 big kernel: [233387.108848] Pid: 11357, comm: rhythmbox Tainted: P 2.6.28-12-generic #43-Ubuntu May 12 08:00:37 big kernel: [233387.108851] Call Trace: May 12 08:00:37 big kernel: [233387.108862] [<c04fca36>] ?
