Data import by Logstash error

Elastic Stack Logstash
#1

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.
