As the other end is down, A will not receive the DELETE reply. And A is entering into retransmitt mode. And all the subsequent stroke messages are in queue,because of retransmission mode.</div><div><br></div><div>When this is going on, I removed "r1~v1" in ipsec.conf and sent SIGHUP, and added back the connection "r1~v1" in ipsec.conf and sent SIGHUP.</div><div><br></div><div>I am seeing all the stroke messages related to this conn[r1~v1] are in queue, and once after 5 retransmitts all the pending stroke messages are executed.</div><div><br></div><div>Queuing the stroke messages when conn is in retransmission mode, Is this expected behaviour?</div><div><br></div><div>Is there anyway to prevent the retransmissions for specific Informationl packets ?</div><div><br></div><div><br></div><div>-Bhargav</div><div><br></div><div class="gmail_signature"></div>
