Does this not cause excessive SAs piling up? I've seen a similar
problem with Strongswan on my side and a MikroTik on the remote side:
too many excessive SAs in "ipsec status" output and in MikroTik's
management console.

My theory was that each trapped packet causes a new SA to be
attempted/generated until some limit is hit or some resource is
