elasticsearch=1.6  
logstash=1.5

Im using docker with supervisord to start up the ELK stack. I tried using ort 514 and port 5009 to listen on the syslog messages coming in but when i run logstash in debug mode i get the follwoing error syslog listener died {:protocol=\>:tcp, :address=\>"0.0.0.0:5009", :exception=\>#\<Errno::EADDRINUSE: Address already in use - bind - Address already in use\> or syslog listener died {:protocol=\>:tcp, :address=\>"0.0.0.0:5009", :exception=\>#\<Errno::EADDRINUSE: Address already in use - bind - not found \> .

Config is  
input {  
syslog {  
type =\> "syslog"  
port =\> 5009

```
    }

```

}

COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME  
java 8 root 90u IPv6 0t0 UDP \*:5514

I had to open a different port inside and out. Even with logstash starting with root it didnt like the port I had open.
