Proxmox6 lxc container fail

[xylle]

Hello,
i have one Promox (up to date) with 18 lxc Container and 1 VM.
one of the containers is a DHCP server, it crashes regularly. I did it all over again, but it still crashes. The container exists since Proxmox 5, it is only since the transition to Proxmox 6 that it fails. All others work without problems. The attachment contains the host log at the time of the crash, no relevant message in the CT logs

Resources :

Memory	512MiB
Swap	512MiB
Cores	1
Root Disk	local-zfs 8G
Memory usage after one day	30MiB
OS	Debian 10.4, up to date
Type	unprivileged
Net	bridge=vmbr0,type=veth

Thx for help

hi,

you're running out of memory (the oom-killer is getting triggered).

have you tried increasing the available memory of the container?

I doubled memory (RAM and Swap ). But after 2 days of operation, I'm still at 27MiB.
The majority of my containers work with 512MiB of memory. The dhcp server is the only one that does this, it's really weird.
