LXC Containers and RAM always maxed out

[Wojciech Szpunar]

Hi,
I'm testing containers in proxmox and noticed some weird behaviour.
I have installed cenos 7 image for test and added just ssh and apache to it.

Then downloaded large iso file to test network connections etc.

Since I have started to download that image from server I have noticed that RAM usage was 100% which was bit weird but ok I could live with that.
But then when download was completed Proxmox is still showing 100% RAM usage on machine even tho I use only 17MB:
[root@bandwidthtest ~]# python ps_mem.py
Private + Shared = RAM used Program

128.0 KiB + 242.0 KiB = 370.0 KiB agetty (2)
572.0 KiB + 191.5 KiB = 763.5 KiB dbus-daemon
584.0 KiB + 217.0 KiB = 801.0 KiB systemd-logind
496.0 KiB + 478.5 KiB = 974.5 KiB rsyslogd
508.0 KiB + 618.5 KiB = 1.1 MiB login
680.0 KiB + 1.2 MiB = 1.9 MiB bash (2)
2.3 MiB + 211.0 KiB = 2.5 MiB systemd
3.9 MiB + 355.5 KiB = 4.2 MiB systemd-journald
2.3 MiB + 2.8 MiB = 5.1 MiB sshd (2)
---------------------------------
17.6 MiB
=================================

See attached image where in same time I get 100% RAM usage on that VM in Proxmox GUI.

Any idea why this chart and value in gui do not match real usage?

Hi,

lxc-top shows also the cache.
Please open a bug.

Thanks
Yes seems like it does include Cache.
See screenshot of lxc container 100 which is the one I have issue with.

I will get bug registered now.
