Any possibility that you have some kind of automatic snapshoting utility run from crontab recursively on filesystem where poudriere have builder jails mounted? I saw this error when I setup zfsnap in crontab with resursive snapshot of /vol0 (each 5 minutes) and my poudriere is in /vol0/poudriere. The workaround was to not create recursive snapshots on /vol0 but on each /vol0 sub-filesystem except /vol0/poudriere. I don't know it this is your problem too. Kind regards Miroslav Lachman
