According to the error the user you are running elasticsearch as can not read (and probably write) to the `/tmp` directly. Elasticsearch like mini programs need to be able to read and write from the `/tmp` directory. You need to fix the permissions on that directory ---

May be you need to check what user is being used for Elasticsearch. Try find the user from the Elasticsearch service unit file. and then run the command provided by stephenb from that user. you can simply do sudo -u {USER} chmod 1777 /tmp ---

@Akhtar_Zaman thanks for the response how to check the user used by elastic what cmd? I think you mean the user that i used to access elastic from kibana is "elastic" i try to do what you told but this is the result ```auto elastic@elastic:~$ sudo -u elastic chmod 1777 /tmp chmod: changing permissions of '/tmp': Operation not permitted ``` ---

No but i used a solution last month it worked with me but now when I used it it did not work see if it work for you the solution is to decrease the the amount of the ram here , you will find 4g change it to 1g or 512m to enter to this file of configyou can use : sudo nano /etc/elasticsearch/jvm.options then save the config and restart elasticsearch ![image](https://us1.discourse-cdn.com/elastic/original/3X/4/a/4ab987fc771af22c0ed5819aa56b1abfbabe56d1.png) ---
