(In reply to Robert Delahunt from comment #34) Please start by cgroup_disable=memory with your current kernel first. If this works around the problem then my theory about proportional reclaim distributed memory pressure to anonymous mostly cgroups would be a good fit. After that is confirmed then it would be great to run with the current kernel. Installing one from http://download.opensuse.org/repositories/Kernel:/stable/standard/ should do it.
