SubjectOOM-killer and strange RSS value in 3.9-rc7
Hi list,

On a power7 system, we have installed 3.9-rc7 and crash 6.1.6. If I run
something like "make -j 64" to compile linux kernel from source, sooner
or latter, oom-killer will be triggered. Before that, when I trying to
analyse the live system with crash, some processes' %MEM and RSS looks
too big:

crash: this kernel may be configured with CONFIG_STRICT_DEVMEM, which
renders /dev/mem unusable as a live memory source.

I'd like to ask if this a problem of the kernel or crash.

Thanks in advance.
