Now I am seeing the following ERROR in Heavy forwarder's splunkd.log
ERROR TcpInputProc - Message rejected. Received unexpected message of size=842019376 bytes from src=X.X.X.X:YYYY in streaming mode. Maximum message size allowed=67108864. (::) Possible invalid source sending data to splunktcp port or valid source sending unsupported payload.
Any idea on how this can be resolved and have a data transfer from indexer to heavy forwarder?
Also, The data that I'm trying to transfer from indexer is not that huge. Doesn't make any sense on the high vollume error message.
