I recently transitioned to a new instance of Splunk and have been having some trouble configuring the new environment.
I have 8 remote Windows hosts with identical forwarders (inputs.conf and outputs.conf are the same on all 8). 5 of the hosts are forwarding information correctly but 3 are reporting: "The TCP output processor has paused the data flow".
After reviewing some of the similar posts, it seems this error message is generic and just says there's nothing wrong with the forwarder, but there's something wrong with the server.
I reviewed the monitoring console but didn't see anything that would indicate the server or index not having the ability to receive more information.
