Hi,

I have a logstash configuration to ingest large number of json files from a directory.  
The ingestion works perfectly fine, But for a particular number of json files.

For example i pointed the input for a folder with 400000 json files and it gets ingested without a problem. But when I point the input for a folder with 1000000 json files, it does not ingest.

Any idea of why this could happen ?

What does your input configuration look like? What version are you using?

There are issue related to large numbers of files, some of which have been fixed ([here](https://github.com/logstash-plugins/logstash-input-file/issues/241) and [here](https://github.com/logstash-plugins/logstash-input-file/issues/219)).

Hi Badger,  
My input looks as follows,

```auto
input {
 file {
 path => "/home/ubuntu/filesPath/*.json"
 sincedb_path => "/dev/null"
 codec => json
 mode => read
 file_chunk_size => 131072
 }
}

```

and the version is logstash 7.10.2

I believe 7.10.2 would have a 4.2.x file plugin. You could verify using

```
cd /usr/share/logstash; bin/logstash-plugin list --verbose logstash-input-file

```

I suggest you point logstash at a folder with a million json files, wait a while, then get a thread dump (kill -3, or jstack, or whatever tool you prefer) and what the runnable threads are doing. If you are unable to interpret the thread dump then post a gist or put it on on some other site where I can view the text and I will see if I can tell what it is doing.
