Briefly, this error occurs when Elasticsearch is unable to start a datafeed within the specified timeout period. This could be due to heavy load, insufficient resources, or network issues. To resolve this, you can increase the timeout value, ensure that the Elasticsearch cluster has sufficient resources (CPU, memory, disk space), and check the network connectivity between the nodes. If the problem persists, consider optimizing your datafeed or reducing the amount of data it processes at a time.
