> [@](#): > > The signal HUP is in use by the JVM and will not work correctly on this platform. This message is not 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). ---
