From b43a57bb4dae72e8f7232e7c821a8799eda30022 Mon Sep 17 00:00:00 2001 From: Kirill Korotaev Date: Wed, 6 Dec 2006 20:32:27 -0800 Subject: [PATCH] [PATCH] OOM can panic due to processes stuck in __alloc_pages() OOM can panic due to the processes stuck in __alloc_pages() doing infinite rebalance loop while no memory can be reclaimed. OOM killer tries to kill some processes, but unfortunetaly, rebalance label was moved by someone below the TIF_MEMDIE check, so buddy allocator doesn't see that process is OOM-killed and it can simply fail the allocation :/ Observed in reality on RHEL4(2.6.9)+OpenVZ kernel when a user doing some memory allocation tricks triggered OOM panic.
