I've been a mod on another forum using VBulletin - usually I saw this happen if I was acting (moving, deleting etc) on a number of posts in a thread and the forum processing would hang up and fail, somewhere in the middle of the process. The posts were no longer in the original thread to be able to re-do the move, and sometimes they didn't show up in the destination thread until more posts were added.
It definitely was the exception, but seemed to happen in large threads that had already seen a bit of modification.
