Thanks for testing it. I think you ran into the similar pre-mature OOM 
issue as what Shakeel reported.

Andrew,

The patch has been in -mm tree 
(mm-vmscan-check-if-mem-cgroup-is-disabled-or-not-before-calling-memcg-slab-shrinker.patch), 
it seems we'd better to get this fix in the upcoming 5.3-rc so that it 
could get into stable release soon.
