Well, that last statement doesn't make any sense.  Keep in mind that / 
is your ROOT partition.  i.e. this means your primary boot partition.  
Now, there's the possibility that you've got a 
/Volumes/Unix/var/spool/news that is a symbolic (what you call soft) 
link to /var/spool/news, but there is not two /var/spool/news 
directories on the system.  does this make sense?  It's good that you 
didn't get any errors on an fsck, but what options did you use when you 
ran it?  Are you using journaling on the UFS partition?  Are you 
_certain_ that it's space and not inodes?  Often, with news servers, 
there are so many small files that you run out of inodes.  check this 
to make sure, possibly post results of df -h and du -d 1 
/Volumes/Unix/var.

This would help greatly.
