We have a roulettecoin-adapted litecoinseeder running to ease the burder on seed nodes. However there are only 17 nodes currently accepting incoming connections, most likely your is one of them and that's why you get a lot of connections (from roulettecoin peers, not litecoin).
Well that's good, but it would be nice if you could change the seeder's version message. I guess it was just a coincidence that a bunch of nodes simultaniously disconnected the one time I was watching the log.
