I have deployed Elasticsearch on a development ubunto VPS. We use that VPS only to host Api for mobile apps.
Everything worked good till today, elasticsearch stops working. I tried to restart it, it says Server ok but when i check the status it gives me : is not running.
The Ruby on Rails app log contains : Errno::ECONNREFUSED (Connection refused - connect(2)) After that, i start getting this error : Too many open files
Does anyone can help me ? Thanks
