Briefly, this error occurs when Elasticsearch fails to stop a task due to an issue with retrieving the deployment ID. This could be due to a network issue, incorrect configuration, or a problem with the Elasticsearch cluster itself. To resolve this issue, you can try the following: 1) Check the network connectivity and settings, 2) Verify the configuration settings for the task and deployment ID, 3) Investigate the health and status of the Elasticsearch cluster, and 4) Check the Elasticsearch logs for more detailed error information.

This guide will help you check for common problems that cause the log ” [” + task.getDeploymentId() + “] failed to stop due to error ” to appear. To understand the issues related to this log, read the explanation below about the following Elasticsearch concepts: plugin, task.

Log Context

Log “[” + task.getDeploymentId() + “] failed to stop due to error” classname is TrainedModelAssignmentNodeService.java.
We extracted the following from Elasticsearch source code for those seeking an in-depth context :


        ActionListener notifyDeploymentOfStopped = ActionListener.wrap(
            _void -> updateStoredState(task.getDeploymentId(); updateToStopped; listener);
            failed -> { // if we failed to stop the process; something strange is going on; but we should still notify of stop
                logger.warn(() -> "[" + task.getDeploymentId() + "] failed to stop due to error"; failed);
                updateStoredState(task.getDeploymentId(); updateToStopped; listener);
