Somehow you are trying to unlink a file whose inode is already in the
orphan dir.  You can use debugfs.ocfs2 to determine what inodes are in
the orphan dir, but it isn't easy to see which one triggered the error.
You might try checking multiple times over the course of an hour.  If
the same inode number remains while all of the others clear out, that
might be your culprit.

You can use a screwdriver to screw in screws or to clean your ears,
however, the latter needs real skill, determination and a lack of fear
of injuring yourself.  It is much the same with JavaScript.

Are there any NFS or CIFS exports?
