Hi,

I have a lot of errors like this (every 5 seconds) :

```
{
  :timestamp=>"2016-09-27T10:36:52.024000+0200",
  :message=>"gelf listener died",
  :exception=>#<SocketError: bind: name or service not known>,
  :backtrace=>[
    "org/jruby/ext/socket/RubyUDPSocket.java:160:in `bind'",
    "/opt/logstash/vendor/bundle/jruby/1.9/gems/logstash-input-gelf-2.0.7/lib/logstash/inputs/gelf.rb:98:in `udp_listener'",
    "/opt/logstash/vendor/bundle/jruby/1.9/gems/logstash-input-gelf-2.0.7/lib/logstash/inputs/gelf.rb:77:in `run'",
    "/opt/logstash/vendor/bundle/jruby/1.9/gems/logstash-core-2.4.0-java/lib/logstash/pipeline.rb:342:in `inputworker'",
    "/opt/logstash/vendor/bundle/jruby/1.9/gems/logstash-core-2.4.0-java/lib/logstash/pipeline.rb:336:in `start_input'"
  ],
  :level=>:warn
}

```

here is my input config :

```
 input {
  beats {
    port => 5044
  }
  gelf {
    port => 12201
    # use_tcp => true
    type => "gelf"
  }
}

```

If I knew which "name or service" it's trying to connect to, it would help.  
For the moment, I have no clue 😕

Thanks for any help.

I've monkey-patched the code and the exception is raised when trying to bind to `0.0.0.0:1220`.
