TCP output processor has paused data flow

[bsantosh]

Hi Team,

I am getting the below error on my newly set Heavy Forwarder:

Tcpout Processor: The TCP output processor has paused the data flow. Forwarding to output group splunkcloud has been blocked for 10 seconds. This will probably 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

Could you please help me with the issue.

regards,
Santosh

Hi ,

This usually happens when a forwarder cannot send something to an indexer. Is splunk running on your indexer? Is the input's port open? Can the forwarder connect to the input's port?
