Robert's description of the mechanics we observed is accurate. We discovered this regression in the oom-killer's behavior when attempting to upgrade our system. The fraction of the system that went unhealthy due to this issue was approximately equal to the _sum_ of all other causes of unhealth, which are many and varied, but each of which contribute only a small amount of unhealth. This issue forced a rollback to the previous kernel where we ~never see this behavior, returning our unhealth levels to the previous background levels. Cheers, -a
