[Podman] What causes 'invalid internal status, try resetting the pause process with "podman system migrate": could not find any running process: no such process'?

Hello all, I see the message 'invalid internal status, try resetting the pause process with "podman system migrate": could not find any running process: no such process' quite often upon executing podman (rootless). In the net I could only find that this can happen after a host reboot. But in my case there is no reboot, so I am curious wich conditions actually have to be met for this message to appear. Yes, after "podman system migrate", I can use podman again, but it might occur just a minute later, or a day. The only observation I had besides the error message is, that after that "podman system migrate" I still see a couple of containers in state "Stopping". With those, podman rm -f always complains that it cannot kill the proces, but at least it can remove the containers. I'm curious if I could prevent that "invalid internal status" completely (because it disturbs my automation), but then I would need somebody explaining to me why this does actually happen. Any hints? -dirk
