When i am upgrading my web HF from 8.0.0 to 8.1.2 then i am getting below error. Please let me what is available workaround for the below issue.
The TCP output processor has paused the data flow. Forwarding to host_dest=<indexer_name> inside output group splunkcloud from host_src=<HF_NAME> has been blocked for blocked_seconds=1970. This can stall the data flow towards indexing and other network outputs. Review the receiving system's health in the Splunk Monitoring Console. It is probably not accepting data.
