Error description
IKEv1 established Phase2 Security Associations (SAs) delete payloads are not being generated and sent to IKE remote partners during IKED address space termination. However the representations of the Phase2 SAs have been removed from IKED when it terminated. In cases where the anchor IKE SA (Phase1) has expired and was deleted and the Phase2 SAs were not, the reported scenario will occur. After IKED is restarted the following messages will be seen in the IKE log because the remote IKE partner is still using the Phase2 SA before the IKE daemon was recycled: EZD0811I Decapsulation failed ........
Local fix
