Hello

It has core-dumped , with UA that used sctpdlib(ua.h).
In this case, the length of the data that received it from the
peer node was 4000 octets.

+--------+ +--------+
| UA | | peer |
|sctpdlib| <- Daemon <- | node |
+--------+ +--------+
core-dump <----- 4000 octets

The length of the data that received it, in UA that used
sctpdlib(ua.h) might become short.
This phenomenon seems to happen in the case that the data of the
length of 1000 octets over is received from the peer node.
In this case, the length of data becomes the same length as the
data that received it before. (?)

+--------+ +--------+
| UA | | peer |
|sctpdlib| <- Daemon <- | node |
+--------+ +--------+
300 octets <----- 300 octets
length mismatch <----- 1000 octets
(300 octests)

This problem did not happen, in the case of UA that used
sctplib(sctp.h).

+--------+ +--------+
| UA | | peer |
|sctplib | <----------- | node |
+--------+ +--------+
receive OK <----- 1000 octets
receive OK <----- 4000 octets

Does special setting become necessary, in the case that SCTP
daemon is used ?


TIA
