Michael,

can we avoid this ? if we call sctp_receiveUnacked/Unsent we get
the SCTP_WRONG_STATE error.

thanks,
Karel

Hi Karel,

the sctplib should wait for all DATA to be SACKed and then
send the SHUTDOWN. This is required by the SCTP state engine.

Best regards
Michael

and if it waits for ACKs, is it possible do discard any unsent
and unacked data so the SCTP library sends the SHUTDOWN imediatelly ?

thanks
Karel

we control the size of send queue. the queue is full because the remote
end does not read. we call the sctp_shutdown.
is the shutdown send immediatelly or does SCTP library wait for ACKs
for already sent chunks ?

thanks
Karel Zabloudil
