I'm having issues with Elasticsearch 1.7.6 I am on a server with 32gb of ram openvz centos-release-6-9.el6.12.3.x86_64 whm/cpanel (but installed elasticsearch via RPM ssh) and am having issues like here: Elastic search fails after some time it runs for a few hours then dies.
There is nothing logged in the elasticsearch.log though I have DEBUG enabled. Elasticsearch runs as user elasticsearch the permissions on the 3 elasticsearch directories in /etc/ lib and log are all correct permissions.
So it seems disabling Sigar can help: https://github.com/elastic/elasticsearch/issues/9582 and https://github.com/elastic/elasticsearch/pull/11293 but how do I do this? Or is there something else you would suggest to do? I have almost default settings for elasticsearch the only change was to uncomment discovery.zen.ping.multicast.enabled: false in the elasticsearch.yml
This is used for activecollab https://activecollab.com/help/books/self-hosted/elasticsearch which requires the 1.7.6 I can't upgrade to 2.x or 5.1.x.
