I thought you said you rebooted in an earlier email, but if you haven't 
it is possible for a process to open a file and remove it's name while 
it is still open.  In this case, the process can still access the data 
in the open file and the space is not released until the last process 
closes it.  Killing the process with the open file (which obviously 
happens if you reboot) will fix that.  Another possibility is that you 
have file system corruption that needs to be fixed with fsck.  This 
should be done with the file system unmounted so the easiest way might 
be to use the -F option to shutdown to force the fsck run at bootup.
