It looks like this is caused by RabbitMQ using port 35357 for its connection to epmd. The default local port range on linux is 32768-61000. In simple mode keystone will attempt to bind to 0.0.0.0.
root@node-8:~# cat /proc/sys/net/ipv4/ip_local_port_range 32768 61000
From the netstat output form the diagnostic snapshot: tcp 0 0 127.0.0.1:35357 127.0.0.1:4369 ESTABLISHED 18490/beam
