Fortunately these files do not contain any data ("size=0") - although they may still be significant to your applications. Try "fsck -p". If that doesn't work "fsck -y". If that doesn't work unmount the filesystem and repeat.

Otherwise, backup data, re-create filesystem ("mkfs") and restore data.

fsck should never be run on a mounted filesystem.  With the exception of root fsck should only be run on unmounted filesystems.  Where root is concerned one should make sure that "all" other filesystems are unmounted prior to running fsck.

Good Luck

fsck on AIX is safe on a mounted filesystem. it may not fix the problem if it is still mounted but it will not do any more harm.
