ElasticSearch switch off

[giorgino]

I installed and run ElasticSearch following the Slavik direction. All working fine, but ES switch off every few hours.

How troubleshoot this?

XenForo_Exception: Elasticsearch server returned no response. Is it running? - library/XenES/Search/SourceHandler/ElasticSearch.php:718

For turn on ES again I have to login via SSH and restart ES with restart shell command.
After few minutes, the same error. I'm really frustrated.

Mike, thank you for this info. I've followed the CentoOS guide (http://pro.benjaminste.in/post/318453669/increase-the-number-of-file-descriptors-on-centos-and) for increase the file open variable
