Memory Leak

Node: 5.6.0 elasticsearch.js: 12.1.3 elasticsearch: 5.0

var client = new elasticsearch.Client({
  host: 'localhost:9200',
  apiVersion: '5.0',
  sniffOnStart: false,
  connectionClass: 'http'
});

When we are using bulk API, we are facing serious memory leak, the app memory reached up to 5.0G.

client.bulk([params, [callback]]) // Just a bulk of 10 records per second.

The app has only this code, so it’s definitely the source. am I the only one who has experienced it?

Alright, I just revisited those metrics I was quoting earlier and it looks like the average is pretty misleading. The processes at the top of the chart above were actually running out of memory and dying, so definitely seems like a memory leak. Thankfully, master (which is now 13.0.0-beta1) is not in that group.

I tested on 13.0.0-beta2, and it works. No more memory leak while I’m using it with rabbitmq to index ~200.000 records from mysql to elasticsearch.
