Elasticsearch Keep Stopping

I am running Elasticsearch 8 on a server with 300gb hard drive and 16gb RAM. The Elasticsearch keep stopping in few hours. I tried restarting it using systemctl and got below message

When I clear the /tmp and try to start it, it works again. Please help

Please check the Elasticsearch logs and post those.

Looks like some permission issue

See if below links help :

There's big gaps in the logs, but there's nothing that even shows Elasticsearch is being asked to shut down, so it's really unclear what is happening.

What do your system logs show at these times?

Can it because of noexec set on /tmp ?

It's possible, yes.

but removing noexec is not good if we look at it for security reasons.

Any pointers for me ?

can someone help me please ?

seems Elasticsearch getting an OOM ? this is from /var/log/messages but this server has only one website and 6 CPU with 16GB RAM.

Can someone help me why this is happening ?

Can you share your Elasticsearch logs from that time?
Did you change noexec on tmp?

I didn't change noexec on tmp as it's a security risk. Let me get the logs of that time
