Other things that I have seen are if you have a FS mounted inside  
your jail and that did not umount completely or appropriately, for  
example.

For example, I use file backed md devices as jail file systems and I  
mount various pieces of a master jail inside my jail.  If I do not  
umount everything cleanly before shutting the jail down it remains  
listed in the jls list
