How to run the reproducer:
1. Install LTP test suite:
  $ git clone git://github.com/linux-test-project/ltp.git; make autotools; ./configure; make; make install
2. Execute the reproducer:
  $ cd /opt/ltp; ./runltp -s memcg_stress_test.sh

The issue doesn't occur on any machine, I just tested it on two machine, one machine is OK, which has 16Gb RAM,
the other machine is crashed, which has 290G RAM, 8 NUMA nodes.

Please let me know if you need more detailed info.
