Briefly, this error occurs when Elasticsearch is unable to manage the data flow due to network congestion or high data transfer rates, leading to packet loss. This can be caused by insufficient resources or improper configuration. To resolve this issue, you can: 1) Increase the network bandwidth or upgrade the hardware to handle higher data transfer rates. 2) Adjust the Elasticsearch configuration to optimize data flow. 3) Monitor and manage the data flow to prevent network congestion. 4) Check for any network issues that might be causing packet loss.
