> Some older versions of linux have a bug that can cause a kernel panic when the LCE attempts to remove a cgroup. It is a race condition so it's a bit rare but on a few thousand node cluster it can result in a couple of panics per day.
> This is the commit that likely (haven't verified) fixes the problem in linux: https://git.kernel.org/cgit/linux/kernel/git/stable/linux-stable.git/commit/?h=linux-2.6.39.y&id=068c5cc5ac7414a8e9eb7856b4bf3cc4d4744267
> Details will be added in comments.
