Support Request: Failed at step NAMESPACE spawning

[upnort]

Proxmox 5.4, fully updated.

I am prototyping three Debian 10 containers.

In two of the systems I see the log spew noted in the thread title. In one system I don't.

Poking around the web indicates the solution is PrivateTmp=false. I configured all three systems with that parameter and performed systemctl daemon-reload. After invoking that change the one system stopped with the log spew while the other two continue.

The three containers are configured similarly. Likewise with the Proxmox hosts.

The log spew is triggered by logrotate.timer.

I could disable the systemd timer and rotate logs through cron.

Regardless of any work-arounds, I want to understand why two systems exhibit the error and one does not.

Thank you.

Try selecting the 'Nested' feature for the container (it should be available on the latest 5.4)

else please post the container configuration

I hope this helps!

I forgot to add in my original post that I had already tried nested.

Mysteriously, one of the systems stopped exhibiting the messages. There were full host reboots some days ago for kernel updates. All systems were rebooted.

I did find on the original behaving system the pve firewall was disabled. I enabled the firewall and I'll watch that system for a few days.

Which config files? There are no discerning differences in /etc/pve/lxc/xxx.conf files.

Keep us posted how it went!

Yes I meant the container config-files (/etc/pve/lxc/xxx.conf)

Of the three Debian 10 test systems, only one exhibits the error message.

Below are sanitized copies of two of the conf files.. I see no significant differences.

All /etc/pve/firewall/*.fw files are identical.
