One of mob spawning mods is derping. Take them out one by one until you figure out which one.

Ohhhh. so that is what entity limit looks like in 1.6.4. I was just looking at the other thread for 1.7.10 and it was talking about no entity indices left. I guess reporting got better on it at least, since the limit seems still in effect.
I knew that packet24mobspawn message looked familiar Thanks for clarifying.

Ah ok, I see. That would be why it happens only with some mods. Good to know.
