Hi,
I have installed elasticsearch 2.3.3 on ubuntu 14.04.
During elasticsearch restart/start I see OK message as below. But when i execute service elasticsearch status it says "\> elasticsearch is not running"
```
root@madhu:/var/log/elasticsearch# sudo service elasticsearch restart
* Stopping Elasticsearch Server [OK]
* Starting Elasticsearch Server [OK]
root@madhu:/var/log/elasticsearch# service elasticsearch status
* elasticsearch is not running
```
I am not seeing any error message log in /var/log/elasticsearch
```
er increasing to at least [65536]

```
My elasticsearch.yml is as below
```
# Set the bind address to a specific IP (IPv4 or IPv6):
#
network.host: localhost
#
# Set a custom port for HTTP:
#
http.port: 9200
```
Could you please let me what could be the reason for elasticsearch to fail to start ?

Never mind what the `service` command thinks—have you confirmed that ES really isn't running (check with e.g. `ps aux`)?
