Well not neccessarily. I hafve encountered the same problem on both FreeBSD and Linux systems. The thing probably is that the filesystem is not fully synced. There is a sync command in unix and I have tried it also. Sometimes it helps sometimes not. Usually there are two solutions: reboot or just wait for a while until kernel corrects the free space that is shown to the user. Anyway, I guess that it is some sort of a buffering feature of the unix systems. My regular situation for this kinda problem is when some filesystem is full and I delete and delete files but no room will appear. After a while, all the room becomes available again. Maybe somebody more familiar with kernel and filesystems can give good explanation to this feature (it definetly is not a bug as otherwise it would have been corrected long time ago).
