He Manish KUMAR,

to avoid that kind of issue, you can also configure Sugar to use a delay process so record will be synchronized with Sugar using a job instead of a live process, so no "live error" message for your customers : https://support.sugarcrm.com/Knowledge_Base/Installation_Upgrade/Installing_and_Administering_Elasticsearch/#Basic_Configuration 

$sugar_config['search_engine']['force_async_index'] = true;

Of course, it does not mean that you have to care about your elasticsearch server status and manage error. But at least, you won't scared your customers.
