SCTP has attempted to retransmit the data maximum allows times, and at this point it will terminate the association. It sends an ABORT notifying the peer of this, but most likely the peer is unreachable anyway. Any message that a peer sends at this point will most likely result in an ABORT to be send back or an association restart. Might as well start fresh. -vlad > Thanks > > PS > -- > To unsubscribe from this list: send the line "unsubscribe linux-sctp" in > the body of a message to majordomo@xxxxxxxxxxxxxxx > More majordomo info at http://vger.kernel.org/majordomo-info.html > -- To unsubscribe from this list: send the line "unsubscribe linux-sctp" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
