Briefly, this error occurs when Elasticsearch tries to terminate a process, but fails due to insufficient permissions or the process being non-existent. To resolve this, ensure that Elasticsearch has the necessary permissions to terminate processes. If the process doesn’t exist, it might have already been terminated or it’s a zombie process. You can use commands like ‘ps’, ‘top’, or ‘htop’ to check running processes. If it’s a zombie process, you may need to kill the parent process. Always ensure that your system is not running out of resources, as this can also cause such issues.
