On starting /etc/init.d/logstash start . It is giving below error

message=\>"An unexpected error occurred!", :error=\>#\<Errno::EADDRINUSE: Address already in use - bind - Address already in use\>, :backtrace=\>["org/jruby/ext/socket/RubyTCPServer.java:118:in `initialize'", "org/jruby/RubyIO.java:871:in`new'", "/usr/share/logstash/vendor/bundle/jruby/1.9/gems/puma-2.16.0-java/lib/puma/binder.rb:234:in `add_tcp_listener'", "(eval):2:in`add\_tcp\_listener'", "/usr/share/logstash/vendor/bundle/jruby/1.9/gems/logstash-core-5.0.0.alpha3-java/lib/logstash/webserver.rb:41:in `run'", "/usr/share/logstash/vendor/bundle/jruby/1.9/gems/logstash-core-5.0.0.alpha3-java/lib/logstash/agent.rb:136:in`start\_webserver'"], :level=\>:fatal}

I have killed services running on 9600 before starting logstash.  
I have disaled SELinux and iptables as well.
