logstash has an at-least-once delivery model, so certain problems can cause it to hang forever. There is more discussion on this [here](https://discuss.elastic.co/t/should-a-full-dlq-queue-effect-logstash-performance-signifigantly/271036/5) and [here](https://discuss.elastic.co/t/logstash-validation-failed-1-no-requests/255379/2). Changing that would require code changes.
