MSRP expert Info: Malformed Packet. But why?

Hi,

I use wireshark to debug msrp traffic. For some msg I got the following expert info:

Malformed Packet (Exception occured)

Severity level: Error

Group: Malformed

The msrp msg is fragmented into 2 segments. First segment has the malformed error. Second frame is not recognized as MSRP and only rendered as TCP frame.

Problem is that the msrp data in both frames is not accessible in wireshark.

Can you see why the 1st msg is malformed and why the 2nd msg is not recognized as msrp?

Thank you
