Logstash error message when using ElasticSearch output=>“Failed to flush outgoing items”

Question

Im using ES 1.4.4 and LS 1.5 and Kibana 4 on Debian. I start logstash, it works fine for a couple of minutes then i have a fatal error. In order to shutdown logstash i have to delete the recent datas stored in ES, that's the only way i found. One more relevant fact is that Elastic Search looks OK, i can see old datas in kibana and plugin head works fine. My output config : output { elasticsearch {port => 9200 protocol => http host => "127.0.0.1"}}

Any help will be appreciated :)

Here is the full error message : Got error to send bulk of actions to elasticsearch server at 127.0.0.1 : Read timed out {:level=>:error}

Your elasticsearch have surpassed storage and it is unable to write new documents coming from logstash, try deleting old indices and then

PUT your_index/_settings
{
  "index": {
  "blocks.read_only": false
  }
} 

I hope this will work for you. Thanks !!
