Neither of these messages is fatal to Logstash. If you are having configuration errors, they are not what is generating these messages. The HUP message is actually from [JRuby](https://github.com/jruby/jruby/blob/915993886ae6663586d893b7d237f750068aceb5/core/src/main/ruby/jruby/kernel/signal.rb#L35). ---
