We have Pivotal Cloud Foundry as a platform and we are sending logs to ELK. So our setup is like we have an F5 load balancer which sends logs to 3 Logstash servers and these 3 Logstash servers send logs to 3 Elastic servers and on one Kibana server.

Problem is I'm seeing the same log repeating 3 times in one document for e.g

As you can see in `syslog5424_host` field host is getting repeated 3 times also in `syslog5424_pri, syslog5424_sd, syslog5424_proc, etc`

I tried shutting down 2 out of 3 Logstash servers and I don't see thing issue again but as soon as I start all 3 of them I'm seeing same repeating pattern.

Logstash config:

```
input {
  tcp {
    port => 10514
    type => syslog
  }

  udp {
    port => 10514
    type => syslog
  }
}

filter {
  if [type] == "syslog" {
    grok {
      match => { "message" => "%{SYSLOG5424PRI}%{NONNEGINT:syslog5424_ver} +(?:%{TIMESTAMP_ISO8601:syslog5424_ts}|-) +(?:%{HOSTNAME:syslog5424_host}|-) +(?:%{NOTSPACE:syslog5424_app}|-) +(?:%{NOTSPACE:syslog5424_proc}|-) +(?:%{WORD:syslog5424_msgid}|-) +(?:%{SYSLOG5424SD:syslog5424_sd}|-|) +%{GREEDYDATA:syslog5424_msg}" }
    }

    syslog_pri { }
    date {
      match => ["syslog_timestamp", "MMM d HH:mm:ss", "MMM dd HH:mm:ss"]
    }

    if !("_grokparsefailure" in [tags]) {
      mutate {
        replace => [ "@source_host", "%{syslog_hostname}"
        replace => ["@message", "%{syslog_message}"]
      }
    }

    mutate {
      remove_field => ["syslog_hostname", "syslog_message", "syslog_timestamp"]
    }
  }
}

output {
  if [type] == "syslog" {
    elasticsearch {
      hosts => ["10.64.20.85:9200","10.64.20.86:9200","10.64.20.87:9200"]
      index => "logstash-%{+yyyy.MM.dd}"
    }
 }
}

```

Any tip where I should look?
