[PVE-User] Kill LXC...

It could be you are looking at a bug we are experiencing weekly for months.

It is some race condition on copying namespaces in netns.

I posted earlier on it, but no reaction.

This seems to be solved in kernel 4.17 and up, so that needs an ubuntu 
18.10 kernel.

The only way to resolve it is - as far as we know - to reboot the system.
