HI,

I"m getting this error after 30 minutes or so, udp port is open but nothing gets indexed until I restart logstash

load looks to only be 100 events a second

**app versions**

```
elasticsearch 5.1.1 all
kibana 5.1.1 amd64
logstash 1:5.1.1-1 all

```

**config**

```
input {
        udp {
                port => 6343
                codec => sflow {}
        }
}

output {
        elasticsearch {
                hosts => ["172.16.0.46:9200"]
        }
}

```

**error message received**

```
