Hi. I am using Logstash for importing data from Oracle to Elastic Cloud. The working environment is macbook. I made a conf file for importing. It works fine(I checked it with Kibana in realtime - I can see graph changed.) After some time later, console shows the error below and stop importing. Attempted to send a bulk request to Elasticsearch configured at '["---:9200"]', but Elasticsearch appears to be unreachable or down! {:error\_message=\>"Connection reset", :class=\>"Manticore::SocketException", :level=\>:error} If I wait, It is working again. I am worry about that the data might be missing with the above error. Can I ignore this error? Also, I googled this error and mac's TCP setting was the answer for others. Even I set the param as they did, the error is still pops. Thanks. ---
