This means that you are using a one-to-many style socket (SOCK_SEQPACKET)
and you provide an association identifier which does not belong
to any association (anymore).

This is from the man page. In case of SCTP socket it seems to miss some
error codes...

So which one is it? The man page seems to need some update.
