Cgroup limits exceeds after sometime

Hello

I have a Linux server having kernel 3.10.

I run 3 containers on server but after few hours cgroups are constantly increasing and once it reaches to limit 65k no further action can be performed on containers.

After rebooting server it comes to normal mode but after few hours it again reaches to max. memory level.

I use below commands for verification:

cat /proc/cgroups | grep memory

find /sys/fs/cgroup/memory -type d ! -path ‘/sys/fs/cgroup/memory/docker*’ | wc -l

Can anyone please advise what could be the probable reason for having such scenario?

Let me know if any further information require.
