Looking for some assistance on a memory leak issue wherein the RAM consumption keeps gradually increasing day by day and within a span of 6 to 7 days, it reaches 100%. (I have to reboot then). Ram consumption graph

The RAM drop is due to reboot. Each reboot is in 5-7 days to time frame. The containers hosted on the node shouldn't be of concern since I migrated them from old server where everything was stable.

OS: Virtuozzo 7.0.16

Kernel: 3.10.0-1127.18.2.vz7.163.46 GNU/Linux

I changed the kernel to an older version in order to check if in case the kernal was an issue but it was of no help.

This is a 128 GB RAM server with 32GB swap (which I now increased to 64GB with swapinesss also set to 30, but again of no help)

For managing the containers, I am making use of virtualizor.

CPU, load, I/O everything is stable.

Found it's a bug in OpenVZ 7.0.16 https://bugs.openvz.org/browse/OVZ-7278

Edit /etc/vz/ploop.conf change to

USE_KAIO_FOR_EXT4=no
