I guess when the academy students learn about the shadow clone jutsu they learn about their chakra being shared among each clone. Based on that casting too many clones can kill you unless you have enough chakra to do it which Kakashi has apparently.

I also LOVED when Kakashi said Might Duy is the coolest shinobi. It mirrors when Kakashi was ashamed of his father and Obito said his hero was Sakumo.
