I see this kind of situation almost every time that I reboot one of
my tunnel endpoints. Usually I see no ill effects. For me, the
systems seem to create one SA and the immediately create another that
then gets used without error.
I've never really thought much about it since things still work for me.
I guess that I've always chalked it up to the oddness of IKE's design.
