Andrei Sekretenko commented on MESOS-9410:
------------------------------------------
The test is still flaky, on the same 16.04 with the same error.
Basically, it reads `/sys/fs/cgroup/memory/memory.stat` and either sees `rss 0`
there... or some silent failure happens when reading/parsing the stats.
> CgroupsAnyHierarchyWithCpuAcctMemoryTest.ROOT_CGROUPS_Stat is flaky.
