Symptom: IKEv2 leaks embryonic SAs which are visible via 'show crypto ipsec sa'. Conditions: In site-to-site VPN scenarios where a peer is allowed to connect via a static crypto map or dynamic map configuration but the entry is mis-configured to not have PFS but the initiator negotiates the tunnel with PFS. This is specific to a child SA negotiation which is possible on a rekey of an existing IPsec SA or the negotiation of additional IPsec SA.
