Though I recall it had been around a long while, it was also certainly bigger than the physical disk it was on, (presumably a sparse file). I just deleted it, & guessed some flag or config file presence/ absence/ corruption etc had somehow triggered it. (No one else would have enabled snapshots on it). As it had hung, crashed or been troublesome lately, I did a foreground fsck rather background, & I think a 2nd fsck -y straight after 1st, which I think fixed some more, (sometimes does). Maybe schedule an outage, take off line & single user { foreground fsck, & repeat till you get a clean run where it fixes nothing || backup & newfs }. Good luck!
