**Hi, i am using filebeat in order to write to a pipeline:**

```auto
input {
    beats {
        port => "5050"
    }
}

output {

    if [message] =~ /value/ {

        pipeline { send_to => [reciving_pipeline]
         }
}

}

```

**and this pipeline is writing to elasticsearch:**

```auto
input {

    pipeline { address => reciving_pipeline }
}

filter {

    json {
        source => "message"
    }

}

output {

        elasticsearch {
            hosts => ["elasticsearch:9200"]
            index => "reciving_pipeline_index-%{+YYYY.MM}"
        }

}

```

and from some reason, i get more and more documents inserted into the elasticsearch although the log file im testing has only 2. in the last try the number was like 728 documents.

anyone knows something about this?
