Hello Tyler, thanksf or the quick answer. That's true, I should have noticed.
I also tried kicking out one node, clearing all directories and then restarting it with the bootstrap option. It received a few files, but just set there in bootstrapping mode (streams always printed bootstrapping without any files open), forever (> 15 minutes). I stopped the applicaiton so it couldn't be load related, and also tried with a fresh cluster restart. What could cause this? (This should ahve the advantage of cassandra choosing a key in my range which splits the range evenly?)
