I've had a badly spool totally run out of free blocks when df showed it still had about 5% free (including the minfree margin). The problem was that all the free space consisted of fragments, which are useless when you try to create a file that is at least block_size-fragsize+1 byte long. Once this happens, your news server grinds to a halt until expire frees up some blocks. --- Truck
