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:
