</div>Not "after some time", but after another (or the same?) peer connects<br>
with the same identity:<br>
<div class="im"><br>

<br>
</div>Have a look at the ipsec.conf "uniqueids" option to see how to handle<br>
multiple clients with the same identity. Maybe the same peer tries to<br>
reauthenticate, but that might be problematic if a uniqueness policy is<br>
in place.<br>
<div class="im"><br>
> 14[IKE] sending DELETE for IKE_SA fqdn_vr[3]<br>
</div><div class="im">> 14[ENC] generating INFORMATIONAL request 0 [ D ]<br>
<br>
</div>And a notify is sent for the old SA, but the peer never responds to the<br>
delete exchange.<br>
