You haven't provide enough information to identify the problem to the
point, but your problems begin here, and for now you can just simply
ignore the forwarding of frametype 2, as your problem are related to the
signaling itself here - i think 0xd is SUS which as the error message
clearly states was not handled properly.

Is that a call that lasted for several days, since the dates would
suggest it. Anyway, the HDLC errors and MTP problems may be your bigger
worries then the forwarding of frametype 2 at the moment.

If you'd provide informations about your setup (especially software
versions you're using) and more consistent logs, it should be easier to
try to help you out.
