I had this too. The server seems to work so I wouldn't worry too much about it. It just takes much time when starting the server.

The reason why these messages appear (or what I think) is that the LOTR mod uses an unconventional item/block ID naming by adding 2 prefixes, eg. lotr:item.lotr:hobbitPancake.
