If a heartbeat chunk is not responded, the global error counter value is increased. If this error value exceeds association_max_retrans, abort the association. But the error counter is also added by T3-RTO, T4-RTO event. Although we know the number of non-responded heartbeats, we also don't know the closer of association destruction. -- Best Regards ----- Shan Wei -- 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
