Failed to create CSV file with 20000 rows

[A3a3e1]

Below is the issue elasticio/csv-component#47
Need to check if it is still a bug

---

I've build a simple integration flow:

then using simple load-test tool loaded 2000 request to it:

#!/bin/bash
loadtest -c 5 -n 20000 "https://in.elastic.io/hook/5de5199b20ea507fdaf1a542?message=Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum"

It run all well:

at the end I expected a file to be uploaded to SFTP to have 20.000 rows in it:

[2019-12-02 14:34:33.287]: The resulting CSV file contains 20000 rows
[2019-12-02 14:34:33.287]: Closing the stream due to inactivity

unfortunately resulting file was only 1 MB large and had 1795 rows in it, not 20000

Attaching result and log of the execution as ZIP file.
