Description (partial)

Symptom:
When there are 2 * IPsec SA and 2 * IKE SA generated for an IPsec selector and when a peer router sends isakmp packet with DELETE payload, the IPsec SAs and one of IKE SAs are deleted but the other one of IKE SAs remains until the end of lifetime.

Conditions:
This behavior is observed with crypto map based tunnel and a peer router sends DELETE because of its idle-time in this case.
