Memory leak on LXC containers

[webix]

Hello.
I recently (3 days ago) updated proxmox to the latest version (4.4-15/7599e35a).
And seems, this version isn't limiting the use of SWAP on the LXC containers.

I have this container running for over 4 months without a problem. Since the update of proxmox, i had to reboot the container 2 times.
The container starts using a lot of RAM, and then SWAP, and he doesn't stop when SWAP get full...
What is annoying is that he starts taking SWAP which should be available for other's containers and for the host himself.
Anyone has a clue on why is this happening?

Host OS: Debian GNU/Linux 8 (jessie)GNU/Linux
RAM: 64 Gb
SWAP: 8Gb

Container: Debian GNU/Linux 8 (jessie)
RAM: 2Gb
SWAP: 512Mb

Check the attached screenshot.
Note: The container template was the one available on the "Templates" button available inside proxmox.

Are you certain it's just not something running inside the container that's the problem?

Well... Ofc if is something running inside the container...
But the container shouldn't ever allow to use more swap than the one allocated to it.
