Hi Maksym, please file bugs in our bug tracker:
https://bugs.wireshark.org/bugzilla/
It would also be helpful if you could check if the bug is still present in
more recent versions (such as the 1.12 release candidate).

Hi all,
I’d like to report a bug in DNP3 dissector for reassembled multi-fragment
DNP3 packets (DNP3 over TCP). In case of TCP retransmissions the DNP3
dissector reassembles invalid DNP3 application layer message by copying the
retransmitted TCP data straight into the final DNP3 packet without checking
if it’s a retransmission or not. As a result the dissector parses DNP3
application layer payload incorrectly. Please find a capture file in the
attachment: here in packet #18 DNP3 transport layer frame 6 (packet #6) is
a retransmission of the frame 1 data (packet #1). Thanks.
