Hello
I have a problem with receiving DLR for some multipart messages.
As I was able to determine, the problem occurs when responses to submit_sm do not arrive in the order in which the parts of the message follow.

As you can see, the first part of the message has seq = 37, the second part has seq = 38.

Responses:

In responses (packets # 27,28), the first packet with seq = 38 (the second part of the message) arrives, and after it the packet with seq = 37 (the first part of the message).

In log I see:

Jasmin use msgid 8e88b4a from second packet, that have seq=37, instead of msgid 479ab700 from first packet with large seq = 38

I'm trying investigate problem, but does not understand submit_sm processing for multi-pdu responses.
Help me please...
