Are you using racoon in ipsec-tools to create labeled SAs?
If so, I recall seeing duplicate SA pairs being created
while using racoon for labeled ipsec. We determined userspace
should manage this.
I posted a patch to ipsec-tools, but I don't think they
ever picked it up... I do not know if this is same problem,
but you could give it a try.

Joy
