HBO6073E Unexpected header. Data rejected.
Explanation
The Data Streamer or Data Receiver discards data from a Data Streamer because the data does not contain a valid header.
Response
If the message is issued by the Data Receiver, verify that the subscriber uses the "CDP Data Receiver" or "CDP Data Receiver SSL" protocol in the policy.
If the message is issued by the Data Streamer, verify that any applications using the Open Streaming API are forming the header properly.
If the problem persists, contact IBM® Software Support.
