Content-Type: text/plain; charset=ISO-8859-15 Content-Transfer-Encoding: 7bit Sender: owner-linux-mm@kvack.org Return-Path: To: linux-mm@kvack.org List-ID: Today, i've meet the oom-killer the first time, but i could not understand why this happens. Swap and Highmem is ok, Could this be a Problem of lowmem and the bigmen (pae) Kernel ? It's a Machine with 2x4 Xeon Cores and 16GB of physical Memory running Debian Etch with Kernel 2.6.18-6-686-bigmem.
