I've never seen anything quite like your report before. I have a similar problem here: 2.5 GB of 6 GB used by ext4_allocation_context according to slabtop. # uname -a Linux ... 2.6.34.7-0.7-default #1 SMP 2010-12-13 11:13:53 +0100 x86_64 x86_64 x86_64 GNU/Linux openSUSE 11.3 > If you do, a couple of questions.
