OK, so the process you dump, what kind of terminal does it use?
Is it something launched under screen/tmux or you just ssh-ed 
somewhere and started?

I'm trying to understand why are terminals involved and -j is not
required.

Yes, I've seen this and the error reported is "inappropriate ioctl"
which means that the descriptor criu tries to set pgrp on happens
to be non-terminal.

W/o logs (or at least images) I am not able to understand why.

If you could strace (with -f) the restoring command and check what
descriptor criu opens to call the TCSETPGRP on, that would be
helpful :)

Let's try to find out on what file CRIU tries to set the group.

Also, please, don't drop the criu at openvz.org mailing list from
Cc when doing replies.

Thanks,
