Hello
We are running logstash 5.6.3, and sometimes it stops inserting data into ES
After restarting the logstash, the data appears in the kibana but the logstash log is filled with messages like this:
[2018-08-02T07:42:03,193][ERROR][logstash.outputs.elasticsearch] Encountered a retryable error. Will Retry with exponential backoff {:code=>400, :url=>"http://my_logstash_instance_name:9200/_bulk"}

there's no errors in ES log
