    statement => "select * from sometable"
    type => "system-refs"
    tags => ["system-refs", "something"]    }   }

output {

Judging by the error message you're getting a connection timeout. Are you sure you're trying to connect to the right port? Can you connect to that port from the Logstash machine using e.g. telnet?
