Upgrade. Upgrade. Upgrade.

We fixed so many things since 5.2.

The current version is 7.13.4.

Sure, @dadoonet. Can you please share details about above error.


5.X has been EOL for quiet some time. Please update as a matter of urgency.

This means you are requesting more data than the heap can handle. So either alter your query, increase your heap, or upgrade.

Simple answer is your cluster is out of RAM. Try reducing the amount of indices you have, that might free up enough RAM on the heap to fix this issue.

Thank you
