I have started the index so many times, but its being closed itself. and  
giving the following error:  
\*  
IndexFailedEngineException[[es\_5][3] Index failed for [RegisteredUser#57]];  
nested:  
FileNotFoundException[/var/lib/elasticsearch/ys-es-0.17clstr/nodes/0/indices/es\_5/3/index/\_9h4.fdt  
(Too many open files)];\*

Can you please tell me what can be the possible cause.

Its not closing itself, you need to increase the number of open files, see  
more here:  
[Elasticsearch Platform — Find real-time answers at scale | Elastic](http://www.elasticsearch.org/tutorials/2011/04/06/too-many-open-files.html).  
Verify that it has been set by executing the nodes info API, it will show  
you the max limit.
