"unregister_netdevice: waiting for lo to become free" after container shutdown

[Stoiko Ivanov]

Just wanted to note I'm having the same issue on pve 6.3-1:

please upgrade to the latest version and reboot - we added a small patch which at least silences the log about the issue (AFAICT it never was a critical error in the sense that anything broke) - since the logging occured roughly every 2 versions and then stopped occuring again...:

I hope this helps

the last i saw this happening it wasn't being shown in the CLI via ssh, but it was still being displayed in the console.

Yes, it will still be in the console. The base issue here is that this is not a single bug, there are a few of those reference counting fixes in every kernel release, and probably a new bug introduced too. Currently, there seems no consensus for a doable way about how to eliminate this class of problem completely, I'm afraid.

For now the issue is resolved after a reboot, hopefully it is fixed for good.
