Invalid Stream Identifier err for DATA message

Hi,

As per RFC 4666  "Invalid Stream Identifier" error is sent if a message is
received on an unexpected SCTP stream (e.g., a Management message was
received on a stream other than "0"). So the err message only received in
response for Management message

But we are receiving the above error message. When we send a DATA message
(i.e. SSA) with not the proper stream id.

Is the behavior correct. if yes please explain.


Attaching the pcap for reference

Thanks,
Santosh
