one host , 2 connections 7111 as master 7112 slave

First 7111 as master and 7112 slave
kill 7111 ...

7112 becomes master without slaves

I start again 7111 and after that i will close 7112

It says that 7111 becomes master without slaves
I can enter to redis-cli -p 9999 but after some test of keys * , redis-proxy sends this error:

events.js:72
throw er; // Unhandled 'error' event
