Index being closed itself

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.
Verify that it has been set by executing the nodes info API, it will show
you the max limit.
