Detecting Migration (with no migration at all...)

[Zamana]

Hello!

I found several threads (here and elsewhere) regarding this issue (or, at least, related to this issue):



The point is that we don't run a cluster/node (so no "migration"), and when a run the command line with strace, I got this:

So, what the command is waiting for?

Proxmox 7.4-17.

Thanks.

Did you ever get an answer?
I have a brand new machine, one node, and have the same issue.
I have searched high and low but found no other users with this issue

Are you going through some kind of (reverse) proxy, firewall, load-balancer of similar to reach this server?
