NUP , Sorry but it does. We were having trouble with lack of space in /tmp
, a few quick comparisons of df an du showed a missing 11 Mg ( a problem 
when the partition is 12 Meg :-). A quick fsck showed all the missing blocks
marked as lost (?) . fsck WOULDN'T reclaim them, we had to destroy and 
recreate the partition (thankfully not to much of a headache under jfs.

But jfs can and does 'loose it'.  We've had other problems in which jfs
is implicated but at the moment we can't quite pin it squarely through
jfs alone.  We tracke out problem down to one program somehow confusing
hell out of jfs and so stopped using that program (screen dammit :-( :-( ).
