Kibana 4 stuck at Loading

Per the docs:

https://www.elastic.co/guide/en/kibana/current/setup.html

This screen never gets to the Create button....it sits at Loading and maxes out the server CPU. After a while I get a Fatal Error:

   Fatal Error

No Living connections

Error: No Living connections

I click "clear session, then I get a blank page and have to restart elasticsearch. Any thoughts on this Devs?

More info from my ES log:

[2015-06-06 08:35:08,146][WARN ][transport.netty ] [Human Fly] exception caught on transport layer [[id: 0xc7164ae6, /192.168.1.253:41342 :> /192.168.1.253:9300]], closing connection
java.io.StreamCorruptedException: invalid internal transport message format, got (5a,56,1,9)

Fixed with larger ES_HEAP_SIZE.
