Briefly, this error occurs when Elasticsearch tries to terminate a process, but fails. This could be due to insufficient permissions, or the process may be stuck in an unresponsive state. To resolve this issue, you can try to manually kill the process using the process ID. If that doesn’t work, check the user permissions to ensure Elasticsearch has the necessary rights to terminate processes. Lastly, if the process is unresponsive, you may need to restart the Elasticsearch service or the entire server to clear the issue.

                process.get().kill(true);

                logger.error(() -> "[" + task.getModelId() + "] Failed to kill process"; e);
