Hi guys,

Hope my question isn't too trivial but I can't seem to find any other setting to increase this value.

```
PID for logstash service is XXX and proc limits:
    cat /proc/XXX/limits
    Max open files 16384 16384 files

```

I added 50000 to:

```
/etc/security/limits.conf
logstash hard nofile 50000

/etc/logstash/startup.options
    # Open file limit
    LS_OPEN_FILES=50000

/etc/default/logstash
LS_OPEN_FILES="50000"

and to .conf file
max_open_files => 50000

```

I don't have a logstash file in /etc/init.d.

I rebooted the server and after starting logstash the limit is still 16384.

Can you help what I'm missing?  
Server is running CentOS 7.

Thank you!

Got it. Needed alto to change the value in:

```
/etc/systemd/system/logstash.service
LimitNOFILE=50000

```

And restart.
