In my case, I am trying to take a backup using dump, and I was able to for e.g., take a backup of /, but failed with /var. Since I use tmux, I know that mksnap_ffs had taken over the machine -- the box was only slightly interactive -- I could type ps axl, but did not get any output. CPU utilisation was at 100% and the only way I could get out of it was to hit the reset button the the box. > > Also no problems when SUJ is disable. +1, I have switched SUJ off and now just have SU on like in 8-STABLE, and am seeing no problems with my backups. Is this a known issue with SUJ -- and is SUJ not yet ready to be used on 9-STABLE?
