From 903091e6af33e8f336fd78e9d9ab178d0761856e Mon Sep 17 00:00:00 2001 From: Stefan Bader Date: Tue, 29 Mar 2011 19:26:56 +0200 Subject: [PATCH] UBUNTU: (config) Disable CONFIG_NET_NS BugLink: http://bugs.launchpad.net/bugs/720095 While network namespaces are used for containers, the implementation was still experimental in Lucid. Even worse the cleanup of network namespaces is very slow. This can cause severe memory issues when an application uses them a lot (for example when cloning subprocesses). The problem can only be avoided by backporting several upstream patches (and without even more changes that will slow down the creation of new net namespaces). This cannot really be justified as a stable update. So turn the option off in Lucid. Users of containers should be pointed to the LTS-backport kernel.
