Hello,
I experience a problem with LXC containers. When I shutdown one of them and attempt to start it again, it stucks and node statistics freeze (question marks in GUI, hanging lxc-info processes in htop). Debug start log file looks like this:
Code:

Please upgrade to the latest available versions (PVE 5.4 has been out for quite some time and even the new major version PVE 6.0 has been out for more than a month) - they include many fixes which could cause your issue.
