The slab can grow unbounded; we've seen it grow larger than 32GB via slabtop. The affected hosts have XFS mounted on / (root filesystem). We have another host running 3.2.0-38 in which we do not see this problem (it has a 37TB XFS filesystem mounted, but not on root). Upgrading to the latest 3.8.0-41 kernel via linux-generic-lts-raring seems to resolve the issue.
