No. one container on system. They are parent-child relationship.

There is only the directory of 4507 in <cgroup mount point>, not exist
the 4506. I print the stuff as follows:

$ ls memory.*
memory.failcnt      memory.limit_in_bytes      memory.stat
memory.force_empty  memory.max_usage_in_bytes  memory.usage_in_bytes

$ cat memory.failcnt
0

$ cat memory.force_empty
cat: memory.force_empty: Invalid argument

$ cat memory.limit_in_bytes
9223372036854775807

$ cat memory.max_usage_in_bytes
1236992

$ cat memory.stat
cache 0
rss 851968
pgpgin 879
pgpgout 671
active 851968
inactive 0


I don't know why memory.force_empty can not be printed the content.


Any idea?
