How to understand "DPNSS/DASS2-User Adaptation Layer"
Wireshark detects DPNSS / DASS2 protocol in SCTP packets.
But it cannot recognize the content of DPNSS / DASS2 protocol.
Please tell me where could the error be?
And how can I figure out what's in DPNSS / DASS2?

There is a pcap attached to "Per-packet memory corrupted" crashes if file contains DUA packets that has a few
DUA
frames.Do they look like the decode information you're looking for?

Are you sure it's DUA over SCTP? Not something else using that ppid?
As stated in RFC4960, the SCTP protocol has no effect on what data it carries. I'm not sure if this is exactly DPNSS / DASS2.
