I get the following response on the issuing server:
curl: (52) Empty reply from server
And this is what shows up in my splunkd log on my HEC server
04-05-2021 14:36:05.026 -0400 ERROR TcpInputProc - Message rejected. Received unexpected message of size=1347375956 bytes from src=<myip>:46804 in streaming mode. Maximum message size allowed=67108864. (::) Possible invalid source sending data to splunktcp port or valid source sending unsupported payload.
I can't imagine my message is really that size. Anyone got an idea what is going on here?
