Auto stop container ?

[IMW72]

Hello !

I have 2 proxmox 6.1 (OVH preinstalled), and on each, some container shudown automatically if not used for some days (I think, it's the only common point).

Is any config to auto-shutdown if no usages ?

The last activity not correspond to backup time or anything.

Thanks all !

Containers are only stopped when the host is shutdown.


journalctl/seslog will help

I've found this in journalctl for the last stop of ctx :

memory: 1024

1G memory is not enough for http server

for this reason you get oom-kill

Sep 17 03:25:33 dev kernel: [15271672.055032] oom-kill:constraint=CONSTRAINT_MEMCG,nodemask=(null),cpuset=ns,mems_allowed=0,oom_memcg=/lxc/150,task_memcg=/lxc/150/ns/system.slice/cron.service,task=chromium,pid=7310,uid=100000

i suggest you to give the container more memory then try again.

 

[IMW72]

I can set more memory but is it really needed ? ...

 

[MihaG]

Hello,

I have the same problem with randomly OOM inside LXC VPS. When the memory usage of the container and the PVE host if relatively low inside Proxmox GUI. Any new info?

Regards,
